Roger Federer says he hopes Carlos Alcaraz can win the upcoming Australian Open and become the youngest man to complete the career Grand Slam.
Six-time major champion Alcaraz, 22, will bid to add the Melbourne title to his two Wimbledon, two French Open and two US Open crowns.
Swiss great Federer completed the career Grand Slam with his 2009 French Open triumph, but by 2004 he had already secured victories at the other three majors.
Completing the set can involve a wait, and Federer said: “It’s like Rory [McIlroy] going for the Masters, those things are tough.”
The 44-year-old told a news conference at Melbourne Park: “At his young age, completing the career Grand Slam would be crazy.
“Let’s see if he is able to do crazy this week. I hope he does because for the game it would be unbelievably special moment.”
