After his gruelling five-set victory over Igor Andreev, world number three Roger Federer plays Gilles Muller of Luxembourg in the last eight

Muller, a qualifier, takes former world number one Federer to a first set tie-break but the Swiss uses all his experience to come through

A crucial break at 4-4 in the second set proves decisive for Federer, who has won the last four US Opens

The big-serving Muller refuses to be shaken off and after forcing the second tie-break of the match he takes a surprise 5-3 lead

But Federer takes four straight points to seal a 7-6 (7-5) 6-4 7-6 (7-5) victory and extend his US Open winning streak to 32 matches

The final match on Arthur Ashe Stadium sees home favourite Andy Roddick take on Novak Djokovic for the right to meet Federer

Roddick has the backing of a vocal New York crowd but it does little to boost his performance and Djokovic races through the first set

After one break proves his downfall in the second set, a badly out-of-sorts Roddick smashes his racket into the ground

Gradually the momentum shifts in Roddick's direction and Djokovic's game and body language begin to crumble under sustained pressure

An early break is enough to seal the third set for Roddick and, much to the crowd's delight, the 26-year-old goes a break up in the fourth

But Roddick serves two double faults en route to being broken back when serving for the fourth set and Djokovic forces a tie-break

Djokovic has the edge throughout an enthralling tie-break and comes through 2-6 3-6 6-3 6-7 (5-7) to set up a semi-final with Federer
