Roger Federer shared his perspective on Carlos Alcaraz's pursuit of a career Grand Slam at the Australian Open. The 20-time major champion said he wouldn't remind the young star about the difficulty of the challenge, comparing it to Rory McIlroy's long wait for a Masters win.

Alcaraz has won every major except the Australian Open, where he's never advanced past the quarterfinals. Federer noted that completing the career Slam at age 22 would be "crazy" but expressed hope it happens for the sport's sake. The Spaniard has dominated Wimbledon and Roland Garros recently.

The current rivalry between Alcaraz and Jannik Sinner, who have split the last eight majors, was praised as "great" by Federer. He highlighted their recent French Open final as potentially one of the greatest matches ever. Sinner still needs a French Open title for his own career Slam.
