Top seeds all through in Dubai except Murray

Andy Murray's surprise loss to teenage sensation Borna Coric yesterday may have been down to his mind wandering to an upcoming Davis Cup tie, according to the thoughts of former Grand Slam winner Andre Agassi. The Scot will shortly join up with his Great Britain teammates for the clash with the United States between 6^th and 8^th March, and with the tie being hosted in Glasgow, the American legend believes that makes it extremely important to Murray. It was noticeable that the Brit was the only one of the top four seeds in Dubai to depart before the semi-finals, with his rivals Novak Djokovic, Tomas Berdych and Roger Federer all taking their place in the later stages of the event.

Former world number one, Agassi told BBC Sport that he believes that Murray was potentially already wanting to prepare "for what he probably is really valuing - that is the Davis Cup." It may become even more of an emotional event for the Murray family in general if, as expected, the two brothers unite for the men's doubles against the Americans.

Murray was completely out of sorts in defeat to the young Croatian, who could surely have not expected such a comfortable 6-1 6-3 victory over the world number three player. By contrast, Djokovic was a class apart from his last-eight opponent in Dubai, as he blitzed the Turkish player Marsel Ilhan for the loss of just two games. He will now face Berdych in the semis, after the Czech had to withstand a second set fight back from Sergiy Stakhovsky of the Ukraine, before triumphing 6-3 4-6 6-2.

Djokovic has yet to lose a set during the tournament and with a massive head to head advantage of 17-2 against Berdych, will expect to make the final.
