Roger Federer crashes out of Madrid Open at last 16 stage

Federer's game was rather flaky and Nishikori capitalised on the Swiss maestro's errors.

The World No.16 snatched the first set despite only winning five points on his opponent's serve.

Though Federer made light work of Nishikori in the second, his game fell to pieces.

Nishikori asserted his authority in the decider, surging into a 4-1 lead before going on to claim a momentous victory.

The result sees Federer drop to No.3 in the world rankings.
