Tennis in the 21st century has been defined by a quartet of extraordinary champions. Roger Federer, Rafael Nadal, Novak Djokovic, and Andy Murray didn’t just win titles—they reshaped the sport’s landscape, trading the No.1 ranking among themselves for an astonishing 18 consecutive years from 2004 to 2022. As of 2026, three of those icons have retired, leaving only Djokovic still battling at the top. With the Serbian star closing in on yet more history, the debates over who truly stands as the greatest of all time have only intensified. Who better to weigh in than someone who faced all four of them in the heat of battle? Enter Tim Henman, the British trailblazer whose insights are as sharp as his volleys once were.

Henman was the face of British tennis before Murray arrived, a beloved figure who climbed to world No.4 and reached multiple Wimbledon semifinals. During his career, he stood across the net from Federer, Nadal, Murray, and Djokovic, collecting first-hand evidence of their genius. Recently, the former Davis Cup stalwart opened up about those encounters, and his verdict might raise a few eyebrows.

Before dissecting Henman’s opinion, let’s briefly revisit what made each member of the Big Four a legend in his own right.

Roger Federer – elegance personified and still the benchmark for many. He captured 20 Grand Slam singles titles, including a men’s record eight at Wimbledon. For 310 weeks he reigned as world No.1, gliding across surfaces with a style that turned tennis into art. Even after retiring in 2022, his grace and sportsmanship continue to elevate the sport. Can anyone watch his one-handed backhand without feeling a pang of nostalgia?

Rafael Nadal – the undisputed king of clay. With 22 Grand Slams, including an otherworldly 14 French Open titles, he built a legacy on brute intensity and spun opponents off the court with his lefty forehand. His 209 weeks at No.1 tell only part of the story; his rivalries with Federer and Djokovic belong to the ages. Who could ever forget that 2008 Wimbledon final?

Andy Murray – the one who broke through in an era of giants. Three Grand Slams, two of them at Wimbledon, may seem modest next to his rivals’ tallies, but his 41 weeks at No.1 and that historic 2013 Wimbledon triumph – ending Britain’s 77-year wait for a male singles champion – cement his place. His dogged determination, even as his body rebelled, inspired a nation.

Novak Djokovic – the youngest of the four, the last man standing, and statistically the most successful. By 2026, he owns 24 Grand Slam singles titles and has shattered the record for most weeks at No.1. Seven Wimbledon crowns already reside in his trophy cabinet, and his quest to equal Federer’s eight at the All England Club remains one of the sport’s most captivating storylines. Even after the other members of the Big Four have bowed out, Djokovic continues to add chapters to his legacy.

Now, what does Tim Henman think of all this? When he sat down with talkSPORT, he didn’t hesitate to name the most complete opponent he ever faced. “For me, Federer was the most complete player that I ever played against,” Henman said. “I played Federer the most and I felt that he had the most complete game, he could play on any surface, had very few weaknesses, and there wasn’t a specific area that you could necessarily attack.” It’s easy to see why. When Henman faced Federer, he encountered a blend of power, touch, and tactical genius that left no obvious openings. A perfect serve, a forehand that could dictate points from anywhere, and a net game that modern baseliners often lacked—Federer had it all.

Yet here comes the twist. Despite that glowing assessment, Henman’s pick for the greatest player of all time is someone else – and he only played against him once. Who could it be? None other than Novak Djokovic.

“I only played Djokovic once when he was young. I think sort of 18, 19, and his game was developing then. He didn’t serve quite so well, but it’s been incredible to watch how their games have developed over the years,” Henman explained. That single encounter clearly left a lasting impression, but it’s the body of work Djokovic has assembled since then that tips the scales. By 2026, Djokovic’s resume glitters with accomplishments: the only man to win every Masters 1000 event at least twice, a double Career Grand Slam, and a head-to-head edge over both Federer and Nadal. His dominance across hard courts, grass, and yes, even clay, makes a compelling case.

Why would Henman separate “most complete” from “greatest”? Perhaps the distinction lies in the difference between a peerless toolkit and an unrelenting, record-breaking career. Federer played the game in a way that felt untouchable, but Djokovic turned tennis into a problem of physics and endurance that no opponent could solve completely. By 2026, with Djokovic still adding slams and refusing to cede the spotlight to the next generation, the numbers are beginning to silence even the most romantic sceptics. Should we measure greatness purely by the aesthetic of a backhand, or by the weight of the silverware?

Of course, debates like this will never be fully settled – and that’s exactly why tennis fans love them. But when a man who traded shots with all four of these titans says Federer was the most complete yet calls Djokovic the GOAT, it’s a perspective worth noting. Henman’s view underlines a truth about the Big Four era: each member brought something unique, but standing on the shoulders of numbers and longevity, Djokovic has edged ahead. As Wimbledon 2026 approaches, all eyes will once again be on the Serbian to see if he can break yet another record. And for those who wonder what it takes to be the greatest, Henman’s word might just be the perfect answer.
