Grosjean stands between Federer and Wimbledon win

Defending champion Roger Federer will tackle Frenchman Sebastian Grosjean today in his bid to secure a place in the Wimbledon final.

If the top seed is successful, he will face either American Andy Roddick or Croatia's Mario Ancic.

Federer has only really been tested by one match in the tournament – his quarter-final against Australian Leyton Hewitt.

Forecasters predict that rain will disrupt play today.
