Wimbledon 2011: Becker on the future of Federer
Jo-Wilfried Tsonga's stunning quarter-final triumph over six-time champion Roger Federer was the biggest shock of this year's Wimbledon.
Tsonga produced a magnificent display to become the first man to come from two sets down and beat the Swiss star in a Grand Slam match.
Federer's total of 16 Grand Slam titles is a record, but at the age of 29 question marks are being raised about how long he will stay in the game.
Six-time Grand Slam winner Boris Becker gives his opinions on the future of Federer in the men's game.
Roger Federer's defeat was not so much about Jo-Wilfried Tsonga going up to another level, but Federer not being able to cope and being unable to find a better stroke.

Three-time Wimbledon champion
It was a big surprise for me. Roger had cruised into the quarter-finals and cruised through the first two sets of this match with some brilliant tennis.
But when it hits you, it hits you.

Roger brought about Pete Sampras's demise when he burst onto the scene and shocked the seven-time champion at Wimbledon back in 2001.
Who knows whether this is the end of the Swiss's era at the top of the men's game?
He is going to have a lot of thinking to do over the summer. Reaching the quarter-finals is not good enough for a six-time Wimbledon champion.
Physically he is still fine despite being 29, but mentally his motivation just cannot be the same as it was three or four years ago.
In order for him to play a couple more years successfully he needs to reach the semi-finals and finals of Grand Slams, that is his quality. He can't be satisfied losing like this.
As a fan I really hope he continues at the highest level and finds his mojo again.more
