Alcaraz career Grand Slam at 22 would be 'crazy' - Federer
Spain's Alcaraz already has six major titles but success on the Melbourne Park hard courts is a glaring hole in his resume.
Should the world number one snap his Australia drought at the tournament starting on Sunday, he would become the youngest man to seal a career Grand Slam.
"At his young age to be able to complete the career Grand Slam already would be crazy," Swiss legend Federer said at Melbourne Park, where he will headline a "Battle of the World No.1s" at the official launch of the 2026 Australian Open on Saturday.
