Roger Federer will retire from top-level tennis after the Laver Cup in London this month.

"My body's message to me lately has been clear," Swiss Federer, 41, said. "I have played more than 1,500 matches over 24 years. Now I must recognise when it is time to end my competitive career."

The 20-time Grand Slam champion has not played since Wimbledon 2021, after which he had a third knee operation.

Only Spain's Rafael Nadal, with 22 majors, and Serbia's Novak Djokovic, with 21, have more men's Grand Slam singles titles than Federer.
