Andy Murray is pleased with his recent command of his temper despite John McEnroe telling him he must control frustrations on court as he begins his latest bid to win Wimbledon.
While the world number four's game has rarely looked in better health, with his run to the semi-finals of the French Open followed by a second title at Queen's Club, his demeanour on court is viewed as being mostly negative.
Murray has been criticised for directing his anger at his support team in the stands, and McEnroe, the game's most infamous on-court ranter, said this week that he believes the 24-year-old is wasting valuable energy.
Murray said: "That's pretty rich coming from him! But it's something that definitely needs to improve. A lot of players have faults. That's something I've tried to get better at.
"A lot of times people think if I shout something in the direction of the box that I'm shouting at them, but if you actually listen to what a say a lot of the time I'm upset at myself.
"I do need to get better and at Queen's I did it very well, the French Open was better so I think I am improving."
The Scot once again carries the mantle of the man who could end the 75-year wait for a British men's singles winner at a grand slam, but there is a noticeably more relaxed air to Murray this year.
Gone is the shy young man who earned a reputation as a surly Scot for his performances in front of the cameras, and Murray feels being at ease with his responsibilities off the tennis court has been an advantage on it.
He said: "It makes the day a little bit less stressful when you're enjoying yourself throughout the day, you're not going through periods where you're not looking forward to doing things. It's definitely helped."
Murray should have little trouble clearing the first obstacle in his path to a first grand slam title when he takes on Spaniard Daniel Gimeno-Traver in the third match on Centre Court tomorrow.
The British number one remains confident he can break his major duck, and he is hoping changes to his diet and preparation can help him overhaul the likes of Rafael Nadal, Roger Federer and Novak Djokovic.
He said of his grand slam hopes on BBC Radio Five Live's Sportsweek programme: "It's a huge motivation for me to keep working hard, to keep working at it. I believe I'll get there.
"I've learned a lot, especially in the last few months, about my game, about my mindset and where I'm at and what I'm going to need to do to get past Roger, Rafa and Novak in the rankings.
"It's an exciting time for me and I'm much more professional than I ever was in the build-up to this Wimbledon.
"I'm taking things like my diet very, very seriously, my training is more specific than it's ever been. The on-court stuff, I feel just like I'm in a better place.
"When I'm on the practice court I'm enjoying it a lot, having fun but working hard and I just feel I understand better now how to approach matches in big tournaments and taking a lot more responsibility."
