Roger Federer says he could continue his career until Tokyo 2020

Federer, 36, has enjoyed a career revival this season after winning the Australian Open and Wimbledon.

There were concerns the veteran could look at retirement after a 2016 campaign fraught with set-backs and a knee injury.

Before this year he had not won a Grand Slam title since Wimbledon in 2012 and didn’t play at the Rio Olympics last year.

But, speaking at a Nike event in Tokyo, the Swiss indicated he could return to the city for the next Olympics instalment.

“I’m staying in Japan for a short period of two days, but the day before I had sushi and shabu shabu, I went to karaoke for the first time and have enjoyed Japan,” Federer said.
