Roger Federer getting the better of Andy Murray in four sets to reach the semi-finals. The 17-time Grand Slam champion seemingly back to his very best.

Federer came in as the six seed and beat the world number four in the first set six, games to three. The reigning Wimbledon champ struggled to make any headway on Federer's serve and went two sets down to Federer. In the third, Murray fought off two match points in the tie break, and prevailed to keep alive his chances.

But Federer didn't let the loss of the set get to him and prevailed in four. He is through to his first slam semi since last year’s Aussie Open.
