Janko Tipsarevic plans "aggressive" performance

World number nine Janko Tipsarevic has revealed that he will look to employ an "aggressive" style against Tomas Berdych this afternoon.

The Serbian has been promoted into the competition following the withdrawal of Andy Murray through injury.

Despite the late call-up, Tipsarevic has insisted that he is ready to perform.

"I'm ready to play," he told Sky Sports News. "I have been practising well.

"The plan is to play as aggressive as possible. I think the better man from the base-line will win."

Tipsarevic must win to have any chance of qualifying for the semi-finals.
