Andy Murray hopes a new coach will help him eliminate the kind of inexplicable dip in form he suffered against Marcos Baghdatis at Wimbledon on Monday.
Murray reached the fourth round of a Grand Slam for the first time
The 19-year-old, who went down in straight sets in the fourth round, hopes to make an appointment by August.
"I struggled to get myself going," he said. "It's happened a couple of times and I need to try and cut it out.
"When I find a coach, I can talk about how I feel, someone to pump you up and get you in the right frame of mind."
He added: "I think I've done a good job on my own.
"But even when I came off after beating Andy Roddick, there were still things I could have better in that match because I let him have so many break points.
"I need a coach to tell me things like that."
I will have days when I play badly but I have to find a way to come though those situations
Murray's defeat ended British interest in the singles, but the 19-year-old denied he has been affected by the added expectation he created by beating third seed Roddick on Saturday.
"I don't think pressure and expectation is a factor," he said.
"It's just something you have to get used to. If five people or 10 million people want you to win, it doesn't matter. The only pressure should be the pressure you put on yourself."
Murray nonetheless looked back on a successful tournament, in which he reached the last 16 of a Grand Slam for the first time and reclaimed the British number one spot.
"I think to get to the second week of a Grand Slam is a very good achievement at my age," he said.
"I have to look at the way I played today and be disappointed - but learn from it.
"I don't want to play like that in Grand Slams. Obviously I will have days when I play badly but I have to find a way to come though those situations.
"I've definitely got a lot of work to do but I've proved to myself I can beat some of the best players in the world in Grand Slams.
"I need to improve physically and mentally but I think by the time I'm 21 or 22, I'll be playing my best tennis."
