[0:00]You know, people always come up to me and and ask about Bjorn, always Bjorn, what was it like playing Borg? Was the 1980 Wimbledon final the greatest match ever? And look, I get it. That rivalry was something special. It was fire and ice. It was rock and roll. It was everything tennis needed at that moment. But here's the thing, nobody actually asks, who was the toughest? Not the greatest rivalry, not the most iconic. The toughest, the guy who made you feel like you had absolutely no answer. Like everything you'd spent your whole career building just didn't work. Those are two very different questions, and the answers are very different too. So today, I'm going to give you six names, some you'll expect, some you won't, and honestly, putting this list together was harder than I thought. Because every single one of these guys, in their own way, made me feel something I didn't enjoy, feeling completely and utterly stuck.
[1:03]Let me start with Bjorn, and I want to be clear Bjorn was my greatest rival, not my toughest opponent, my greatest rival. There's a difference, and it matters. Before I even got on tour, I used to watch him this Swedish kid with the headband and the long hair, girl screaming outside the locker room, walking around like he owned every court he stepped on. I remember thinking I want some of that, I want to be that guy. He was my hero before he was my opponent. And then we started playing each other, and that's when things got complicated. Here's what made Bjorn so incredibly difficult. It wasn't his forehand, it wasn't his footwork. It was the fact that he felt absolutely nothing. Or at least that's how it looked from the other side of the net, you couldn't get inside his head because there was no door to knock on. Every trick I had, the theatrics, the intensity, the emotional pressure, none of it touched him, zero. I built my whole game, my whole on-court persona around the idea that I could affect the moment, that I could make the crowd feel something, make my opponent feel something and, um, with every other guy, that worked. With Bjorn I had nothing. He just stood there baseline, hitting the ball back, again, and again, and again. And here's the strangest part, he's the only opponent I never lost my temper against. Not once. Something about him made me want to be better. Not just play better, actually be better. I remember a moment in New Orleans in '79. I was being a jerk on court, which look wasn't unusual for me back then, and Bjorn actually called me up to the net. I thought he was going to tell me to cut it out, give me some lecture. Instead he put his arm around me and said, just enjoy yourself. And my first thought was he's trying to mess with my head, but later I realized he actually meant it. Um, that was just Bjorn. 1980 Wimbledon final, I had him, I genuinely believed I had him. That fourth set tie break, I still think about it. I could taste it. I thought I was going to win that match and change everything. Instead he found another gear the way only Bjorn could and took the fifth set. It still sticks with me, I'll be honest with you. A year later I finally beat him at Wimbledon and a few months after that he retired. 26 years old, 11 Grand Slams, just walked away. I called him more than once. I told him he couldn't do this, that the game needed him, that I needed him. He was gone. He made me a better player. I would have preferred he kept playing even if it cost me the number one spot and I mean that.
[3:44]Look, I, I'm going to be straight with you. Jimmy and I did not like each other. I think we both know that. I think the whole world knew that, and honestly, I think that's exactly why our matches were so good. With Bjorn there was respect and admiration underneath everything. With Jimmy there was none of that. It was just friction. Pure, ugly, beautiful friction. And it made for better tennis than almost anything else I was part of. But here's what I had to learn, and it took me longer than it should have. Jimmy was genuinely, deeply, frighteningly difficult to beat.
[4:22]Not because of some magical technique, not because he had the most elegant game on tour. He didn't. What Jimmy had was something you cannot teach, cannot practice, and cannot fake. He simply refused to lose. Every single point, every single game, every single set Jimmy came at you like it was the last thing he would ever do on this earth. No moment was too small, no point was throw away. You could be up by two sets and he would still be running down balls that had no business being retrieved, still screaming, still pushing, still making you feel like you hadn't won a single thing yet. I used to stand in front of the mirror before matches and ask myself one question, am I trying as hard as Jimmy? And the honest answer more often than I'd like to admit was no. The only player I've ever seen who brought that same level of effort, maybe even a little more, is Rafael. And even then, it's close. We don't like each other, I've said that publicly and I meant it, but I also said this and I meant it just as much. I always respected Jimmy. Every time I walked off court after beating him, I knew I'd actually earned it. There were no gifts from Jimmy, not one. I hope I made him better. I know he made me better, and that's the thing about enemies sometimes they teach you more than your closest friends ever could.
[5:41]Ivan and I were never going to be friends. That was, that was clear from pretty early on. We were just two completely opposite ideas about what tennis should look like. I believed in touch, in feel, in reading the moment and doing something unexpected with it. Ivan believed in hitting the ball harder than the last time, and then harder than that until you simply ran out of answers. And here's the thing, I hated admitting on clay, I always ran out of answers. What made Ivan so difficult was not that he was more talented than me. I don't believe that. What made him impossible on that surface was that he had no off switch, no emotional lever you could pull.
[6:27]No moment where you could feel him hesitating or doubting, he just processed the situation and kept going. Like a machine that had been built specifically to make my life miserable on slow courts. Yeah, I called him a robot, I said it publicly, I said it more than once, and look, I'm not taking it back entirely, but, um, maybe robots are hard to beat. Maybe I should have been a little more robotic myself instead of relying on inspiration every single day. Now, the match, the one that still haunts me, Paris, 1984, French Open final. I was having arguably the greatest season any tennis player had ever put together. I was playing out of my mind, and in that final I came out and played some of the best tennis of my life in the first two sets. Um, I had Ivan exactly where I wanted him. Everyone in that stadium knew it was over. Then a cameraman moved at the wrong moment. My concentration broke for just a second, and Ivan being Ivan felt the shift immediately and never let go of it. The crowd that had been cheering for me when I walked out slowly turned, point by point, game by game, they moved toward him. And, uh, you know, when I lost that fifth set, I walked off that court without turning around, without acknowledging them. I couldn't. To this day that match haunts me more than almost anything else in my career. Roland Garros was the one Grand Slam I never won, the one that got away every single year, and, um, Ivan is the biggest reason for that. Not the only reason clay was never my best surface and I'll own that, but Ivan on clay was a completely different level of problem. Some guys beat you on the day, I've said. He beat me for a whole decade on clay, and that's the truth as much as it hurts to say it out loud.
[8:17]Boris, let me tell you about one day in Hartford, Connecticut in 1987. Because if you want to understand why Boris is on this list, you really only need to know about that one day. It was a Davis Cup tie, United States versus Germany. The stakes were enormous. Whoever lost was getting relegated out of the world group. Um, I was the American, playing at home with the crowd behind me. Boris was 19 years old, had just lost shockingly early at Wimbledon and had absolutely nothing to lose. Nobody gave him much of a chance, including honestly me. I came out sharp, I took the first set comfortably, and then we got deep into the second set and I had him. I genuinely had him. I was leading 10 games to nine, and there was a backhand volley, the kind of volley I'd made 10,000 times in my career. Easy. Routine. The kind of shot you don't even think about. I missed it. And in that exact moment, something shifted. Boris felt it, I felt it, the whole building felt it. He later said that was the moment he realized I was, in his words, getting shaky. And he was right, because once I missed that volley something left me that I couldn't get back. We played for six hours and 21 minutes. Six hours. The second set alone lasted nearly two and a half hours. By the time it was over, Boris had won, and the United States was relegated from the world group for the first time in history. I gave it all I had, I said afterward, and that was true. Every single thing I had, I left on that court in Hartford. What made Boris so dangerous was not just the serve, though the serve was enormous. It was the fearlessness. He played every point like he had nothing to protect and everything to gain. That kind of energy from a 19-year-old is almost impossible to prepare for. Sometimes that's just not enough, especially when the other guy has absolutely nothing to lose.
[10:19]Now, here's one that might surprise people, Stefan. Not because Stefan wasn't great, he absolutely was, but because when you look at the overall record between us, it looks reasonable, competitive, like two guys who split things pretty evenly over the years, and on paper that's sort of true. But here's what the paper doesn't tell you. In the matches that mattered most on grass, at Grand Slams, in the moments where everything was on the line, Stefan had the edge. And and that's what I remember. You want to talk about strange? Stefan and I played essentially the same game. Same instincts, same net approach, same belief that the point should end quickly and at the net. We were built from the same blueprint, and yet somehow he kept finding ways to close doors that I thought I'd already opened. With Bjorn, I couldn't crack the emotional wall. With Ivan, I couldn't outlast the machine. With Stefan, I couldn't out-execute the guy who was executing exactly what I was trying to execute. That's a very particular kind of frustrating. And here's what made it even stranger. We share something that no other two players in the history of this sport can claim. We are the only two men to have held the number one ranking simultaneously in both singles and doubles. Like two versions of the same player, except his version kept beating mine on grass, which happened to be my favorite surface and the place I felt most at home. Wimbledon 1989, I was coming back strong, playing some of my best tennis in years, genuinely believing this could be my tournament. Um, Stefan stopped me in the semi-finals on grass. On my grass. The most frustrating thing about playing someone who plays exactly like you, you cannot complain about their style, it is your style. On paper, the overall numbers look okay for me, but in the matches that mattered most he was ahead, and that honestly is what I remember.
[12:19]Okay, here we go. This is the one people don't expect. Everyone assumes the answer to toughest opponent is Bjorn. And I understand why, the rivalry, the matches, the history, it's all right there. But I already told you Bjorn was my greatest rival. Toughest? That is an entirely different question. And the honest answer, the one I've had decades to think about, is Pete. I know, I know. Pete and I were both Americans, both loved Wimbledon, both believed in attacking the net and finishing points quickly. On the surface, we should have been cut from the same cloth, and in some ways we were. But here is where it gets complicated. Pete arrived on tour just as I was entering the later years of my career. I was in my early thirties, he was 19, 20 years old. And from the very first time we played, I felt something I was not used to feeling on a tennis court, completely and utterly helpless. His serve was unlike anything I had ever faced, and I had faced some enormous servers in my career. But Pete's was different. It wasn't just the pace. It was the placement, the variety, the way he could hit any spot on the service box at any moment with complete confidence. My whole game was built around reading the situation, taking time away from my opponent, controlling the net, Pete's serve took all of that away from me before the point even started. It felt like I just had the racket taken out of my hands. I've said that before and I'll say it again, because there is no better way to describe it. It didn't matter what I tried. It didn't matter what adjustments I made. He served big, he hit the ball hard, and I simply could not do my thing. And here is the part that really stings. I never beat him. Not once, zero. Across every match we played, I could not find the answer. Not a single time. With Boris, I was older and Boris was fearless and young. That I could at least explain to myself. With Pete there was no comfortable explanation. He was not reckless. He was not lucky. He knew exactly what he was doing and he did it perfectly every single time we met. Later at an exhibition, someone asked me the same question you're asking me now. I didn't hesitate. Um, of all the players I ever played, Pete was the toughest guy, and I meant every word. Some losses teach you something useful, that one just reminded me that time only moves in one direction, and Pete arrived at exactly the wrong moment for me anyway.
[14:56]So there you have it. Six names, six very different kinds of difficult. And look, sitting here now, going back through all of it, Bjorn, Jimmy, Ivan, Boris, Stefan, Pete, I notice something. Every single one of those guys, in their own way, was showing me something about myself that I didn't particularly want to see. Bjorn was ice cold and I was fire. Bjorn showed me that emotion, as powerful as it was, had a ceiling. Jimmy never stopped fighting, and I showed up on talent. Jimmy showed me that effort is its own form of genius. Ivan was all discipline and no inspiration, and I was all inspiration and no discipline. Ivan showed me what consistency actually costs. Boris had nothing to lose and everything to gain, and I had everything to lose and forgot what it felt like to be fearless. Stefan played my own game back at me and did it with a calmness I could never quite find. And Pete, Pete simply showed me that time waits for nobody, not even the number one player in the world. Maybe the toughest opponents were never really about tennis. Maybe they were mirrors. Each one reflecting back a version of myself I hadn't figured out yet. Would I change anything? Honestly, um, I'd probably still argue with the umpire. Some things never change. Um, but I would push harder. I would push longer. Um, I would treat every single one of those matches like it was the last one I was ever going to play. Because those six guys, they treated every match against me exactly like that. You cannot be serious if you think this list was easy to make.
