London: Roger Federer and Novak Djokovic face young and restless Milos Raonic and Grigor Dimitrov for places in the Wimbledon final today as men's tennis reaches a potentially game-changing moment in its history.

In the space of 24 hours at the All England Club, the big four of the game were reduced to the big two following the shock exits of Rafael Nadal and defending champion Andy Murray.

Suddenly, Dimitrov and Raonic have the opportunity to tip the balance in favour of the next generation by breaking down the door which has been frustratingly ajar for a decade. But the odds are stacked against them.

Federer is a seven-time Wimbledon champion will be playing in his 35th Grand Slam semi-final and ninth at the All England Club. Djokovic’s 2011 Wimbledon title was just one of his six majors and he will be playing in his 23rd last-four at a Grand Slam and fifth in a row in London.

Federer has a 4-0 career lead over Raonic, the first Canadian man in the semi-finals in 106 years. He will be the sentimental favourite today against eighth-seeded Raonic.
