Defending champion Roger Federer will be aiming to extend his incredible record on grass when he plays Sebastien Grosjean in the semi-finals on Friday.

Federer is unbeaten in 22 matches on the surface and is odds-on favourite to reach his third Grand Slam final.

The 22-year-old has looked untouchable so far this year and only dropped his serve for the first time in the quarter-final against Lleyton Hewitt.

On the previous two occasions he has reached the last four of a Grand Slam, Federer has gone on to win.

The Swiss is able to dominate from the baseline or the net and, despite not being the most powerful player, has a superbly accurate serve.

Grosjean goes into the semi-final as one of only two players yet to drop a set so far at Wimbledon.

The French number 10 seed, who also made the last four last year, is aiming to reach his first Grand Slam final in four semi-final attempts.

Grosjean's game is well suited to grass - he has a big first serve, an excellent return and his athleticism around the court makes him a real threat.

He can also draw comfort from the fact that he leads Federer 2-1 in matches between the two players, although they have not met since 2001.
