Tim Henman believes Andy Murray will need time to develop a relationship with his new coach once a replacement for Mark Petchey is appointed.

Murray, 18, parted company with Petchey last week following a "difference of opinion" after 10 months together.

Given Murray's sharp rise in the rankings, his next appointment as coach is seen as crucial for his career.

Henman believes it takes time for a player and coach to form an understanding, and said: "If you are starting a relationship from scratch then it's inevitable that it's going to take a little bit of time. But that's Andy's decision."
