Andy Roddick has backed Andy Murray to have a glittering Grand Slam career.

The American former world No 1 shocked third seed Murray in the Wimbledon semi-finals to set up a third SW19 final showdown with Roger Federer, a repeat of their 2003 and 2004 clashes.

Roddick said: "Murray's going to break through and win one of these, probably numerous. In my mind it's a matter of time. It's not if, it's win.
