Andy Murray has admitted that he was disappointed with his performance against qualifier Michael Berrer earlier today.

The British number one was taken the distance by Berrer, eventually edging the German out in three sets.

Despite progressing to round two of the Dubai Tennis Championships, Murray was disappointed with his ability to hold his serve.

"It was a frustrating match because I was up a break in the second set, and I gave it back," said Murray.

"In the third set, again I went up a break and gave the break straight back. So I could have made it a little bit easier for myself if I played a bit better."

Murray will play Switzerland's Marco Chiudinelli in the next round.
