World no. 1 Novak Djokovic will play against British no. 1 Andy Murray at the Dubai Championship semi finals.
Djokovic defeated compatriot Janko Tipsarevic 6-1 7-6 while Murray beat fifth seed Tomas Berdych 6-3 7-5.
Murray was in confident mood after ending a three-match losing streak against the powerful Berdych, with Murray’s only previous win was in 2005.
Four-time champion Roger Federer beat Mikhail Youzhny 6-3 6-4 in the other half of the draw and will now face Argentinian Juan Martin del Potro .
The 2009 US Open champion from Argentina caused an upset by beating fourth-seed Jo-Wilfried Tsonga 7-6 (7-1) 6-2.
Federer has beaten Del Potro nine times in their 11 matches but one of those losses was in the 2009 US Open final.
“I would like to get the chance to play him again,” said Murray of Djokovic. “I had a great match with him in Australia, and hopefully can reverse the result.
“Any time you get a win against the number one player in the world it’s important, because you don’t get a chance to play them that often.”
