Andy Murray is into the quarter-finals of Wimbledon for the eighth year in a row.

The British No 1 needed to show impressive patience and counter-attacking to beat Ivo Karlovic 7-6, 6-4, 5-7, 6-4.

Murray will take on Canadian Vasek Pospisil, who beat Britain's James Ward on Saturday, in the last-eight on Wednesday.

This year's Wimbledon championship is the furthest Pospisil has advanced in a Grand Slam, having previously peaked at the US Open with two third round finishes.

However, he did win the Men's Doubles at SW19 last year alongside American Jack Sock.
