Andy Murray wary of Marin Cilic threat

Andy Murray has insisted that he is fully prepared for a tough match when he faces Marin Cilic in the fourth round at Wimbledon.

The British number one watched on as Cilic was taken to the limit in the third-round by Sam Querrey in what was the second-longest match in Wimbledon history. Despite the Croat's fatigue, Murray is well aware of his opponent's ability.

"We played each other growing up in the juniors," Murray said. "I have known him for a long time.

"He had some knee surgery but has come back well. He had a long match with [Sam] Querrey and I'm hoping he will be tired.

"But guys have come back from long matches before, like Novak [Djokovic] in Australia this year."

The two meet on Court Number One today.
