Roger Federer to retire after Friday’s London match 

Tennis champion Roger Federer has confirmed the final match before his retirement will be the doubles at the Laver Cup in London on Friday night. 

Federer, a 20-time Grand Slam winner, has struggled with a knee problem and does not feel able to play singles. Last week he announced he would retire with a team event. 

He hopes to be teamed up with old rival Rafael Nadal. 

Federer’s retirement announcement comes just weeks after fellow tennis legend Serena Williams retired.
