"If you look at the playing styles of Djokovic, Federer, and Nadal, Novak doesn't possess even one-half of what the other two have," Mouratoglou stated on the High Performance podcast on 29/1.

"Roger is a genius, possessing many qualities. Rafa is a physical force," noted the former coach of Serena Williams from 2012 to 2022. "Novak, however, performs everything well, yet no single aspect truly excels. He is the greatest player because of his unparalleled professionalism, which sets him apart. His incredible attention to detail is unmatched."

The trio dominated men's tennis for 15 years, collectively securing 66 Grand Slam titles. Djokovic holds the record with 24 majors. Federer and Nadal retired in 2022 and 2024, respectively, while Djokovic, at age 38, continues to compete strongly. He will face Jannik Sinner in the Australian Open semifinals on 30/1.

Mouratoglou, who guided Serena Williams to three Wimbledon championships and an Olympic gold medal during his decade coaching the American legend, believes Djokovic, despite a slower start and less superior skills, is the best.

"People err, believing greatness is solely about talent and skill. That is entirely incorrect," Mouratoglou added. "Djokovic is the greatest player. The debate persists because individuals favor other players. However, his achievements surpass those of any player in history across all levels."

Federer and Nadal were already winning machines before Djokovic made his mark. When "Nole" won the Australian Open in 2008, it marked the first Grand Slam in three years not claimed by Federer or Nadal. Subsequently, Djokovic progressively surpassed the two veterans, monopolizing nearly every record in men's tennis.

"He entered tennis when Roger and Rafa were winning everything. All other players considered winning a Grand Slam impossible," Mouratoglou recounted. "He declared he would defeat them. Initially, the media criticized him, saying, 'Who does this guy think he is? He's too arrogant.' Later, Djokovic demonstrated he wasn't arrogant, but possessed extraordinary self-belief."
