Roger Federer to retire after Laver Cup in September

After the Laver Cup in London later this month, Roger will retire from top level tennis.

After having a third knee operation, Swiss tennis player Roger Federer did not play again.

"My body's message to me lately has been clear," Federer said.

Over the course of two decades, I have played more than 1,500 games. I need to know when it's time to stop competing.

He said he loved the game of tennis and would never leave it.

Since the start of the year, only three of the 11 Grand Slams have been staged because of a knee problem for Roger Federer.

He hasn't played a match since he lost to Hurkacz at Wimbledon.

He had previously had two operations on his knee and decided to have another one.

Only Spain's Rafael Nadal and Serbia's Novak Djokovic have more men's Grand Slam singles titles than the Swiss maestro.

He won his first Grand Slam title at Wimbledon in 2003 when he was just 16 years old.

He ends his career with a record number of victories at the All England Club.

He became the second oldest man to win a major singles title in the Open era when he won the Australian Open.

After rising to world number one for the first time in 2004, he spent more time as the leading player on the tour than any other player in the history of the tour, until he was surpassed by Serbia's Novak.

There's more to come.
