Andy Murray intends to have a fun time right through to the Wimbledon final.

The British number one will play Viktor Troicki of Serbia in the third round on Saturday after demolishing Ernests Gulbis in straight sets on Thursday in ruthless fashion.

And while he could not be more serious about his chances of making history by becoming the first British men's champion since Fred Perry in 1936, he puts his relaxed mood and convincing form partly down to his zany training routine which yesterday saw one of his fitness trainers walking around in a cricket helmet.

It is all part of the bets and forfeits his team, led by coach Miles MacLagan and trainers Matty Little and Jez Green, play for on the practice court and which are designed to ease the tension.

Murray explained: "The thing that's important at these tournaments is to do what you do every other week of the year, not change things because it's Wimbledon.

"You just try to act like you do every other week. We play football to warm up. We do the same thing here. We do forfeits and joke around and have fun like we always do. We do that when I'm playing in Doha or whenever.

"My trainer was walking around with a cricket helmet on yesterday. If someone asks what it's for you're not allowed to tell that you've lost a bet. You just have to say you like it.

"We play for different stuff every week. The locker room attendant here has given us some cricket pads and cricket helmet, cricket bat, so it's kind of Ashes-themed forfeits.

"When you start changing things you start to worry about everything that's going on around you. If you just act normal you deal with things better."

Murray, who will go into the Troicki clash with confidence having beaten him in two previous matches, admits he tries harder to avoid the forfeits such as having to get lunch for everyone, while accepting extra push-ups or more bizarre ones such as "kissing the other guys toes."

All silly perhaps and certainly different from the Federer regime, but it obviously works for Murray, who revealed yesterday he had received a good luck message from the Queen.

He also reiterated his dismay at being the only Briton left in the singles after Elena Baltacha slipped tamely to a second round defeat.

Murray said: "It's important everyone understands this is where we're at. We can't go along accepting the results we have had. It needs people in charge to come out and say: 'This isn't acceptable. It's not good enough and this is what we're trying to do to get better.

"I'd rather there were more British players left in the tournament."
