Roger Federer's former coach Ivan Ljubicic recently gave his take on the Greatest Of All Time (GOAT) debate. But it has not gone over well with tennis fans, drawing criticism from Novak Djokovic's supporters in particular.Ljubicic said that, in his opinion, the best-ever tennis player was someone who had the greatest impact on the sport. He cited basketball legend Michael Jordan as an example, noting that despite him not being the most successful statistically, Jordan is widely regarded as the greatest due to his profound influence on the sport.Similarly, Ljubicic believes that despite Djokovic's achievements, Federer's legacy is in a league of its own."You may not be objective in this. For me, the best is the one that has had the greatest impact on your sport. Novak is the most successful. He has all the statistics, but there is a difference between being the largest and the most successful," Ljubicic told Tages-Anzeiger."Michael Jordan was not the most successful, but everyone considers him the greatest for his influence on the sport. Not all of us have to agree. What Novak has done does not tarnish what Roger did," he added. According to a fan, based on Ljubicic's criteria, Andre Agassi should be considered the best-ever player given his unrivaled impact on popularizing tennis."Well then Agassi has made the most impact on tennis if having this criteria in mind. Nobody else has attracted so much attention to tennis as him throught two decades," the fan tweeted.Andrii LA@ALattwitt@TheTennisLetter Well then Agassi has made the most impact on tennis if having this criteria in mind. Nobody else has attracted so much attention to tennis as him throughout two decades.24@TheTennisLetter Well then Agassi has made the most impact on tennis if having this criteria in mind.

Individual sports aren't the same as team sports!" a fan commented.Pablo Borgialli@PBorgialli@TheTennisLetter What's the point of such a comparison? Individual sports aren't the same as team sports!12@TheTennisLetter What's the point of such a comparison? Individual sports aren't the same as team sports!"Michael Jordan comparison is a bad argument. Basketball is a team sport, the greatest player still depends on his teammates. If basketball was individual sport most likely MJ would be the the most successful as well," another fan chimed in.Goran Predovic@gorannnnnnnnn@TheTennisLetter Michael Jordan comparison is a bad argument.

Those players with more titles than MJ was before the modern NBA, and can’t compare a team sport vs individual sport. He needs to quit, 20 ain’t bad 🙄35@TheTennisLetter Again? 2nd time Ljubicic has tried this specious argument, now using Michael Jordan‘s accomplishments to bolster it?

Talking about impact on tennis, PTPA had more impact than any single player in the history of the sport. Just ask people who know - the tennis players.

Artistic performance maybe? 🤡Novak Djokovic falls short of equaling Roger Federer's Wimbledon title recordCarlos Alcaraz defeated Novak Djokovic in the Wimbledon 2023 finalCarlos Alcaraz defeated Novak Djokovic 1-6, 7-6(6), 6-1, 3-6, 6-4 in a four-hour and 42-minute long final clash at the 2023 Wimbledon Championships. With his defeat, Djokovic fell short of joining Bjorn Borg and Roger Federer as the only players to win five consecutive titles at the grasscourt Major.Alcaraz's victory also prevented the 23-time Grand Slam champion from equaling Federer's record of eight Wimbledon titles. The 36-year-old is currently tied with William Renshaw and Pete Sampras, having won seven titles at SW19.During the 2023 edition of the grasscourt Major, Federer had expressed his desire to see Djokovic draw level with his title record at Wimbledon, saying that the Serb's victory would add to tennis history and further elevate the sport on a global level."So, I hope he does it to be honest because I think anything more he does adds to tennis history. It goes above and beyond just talking tennis, it goes into global sports like when he went to 23 in Paris. This is incredible stuff, great news and its good for the game," he said at the time.
