Andy Murray admits he will find it hard to contain his emotions should he go close to glory at London 2012.

The world number four tennis ace broke down in tears in front of millions of TV viewers after losing to Roger Federer in the Wimbledon final just 13 days ago.

And the four-time Grand Slam runner-up is prepared to put his fans through an emotional rollercoaster once again as he bids for Olympic gold.

"I've always been very emotional, I just try not to show it in front of the cameras and in front of millions of people," said the Scot.

"It is pretty uncomfortable at the time when you cannot control your emotions in front of everybody watching.

"But I'm sure if I get close to winning medals or winning the Olympics, then yes I wouldn't be surprised if there are some more emotions."

The 25-year-old insists the injury to Rafael Nadal, ruling the Beijing gold medallist out of the Games, will have no affect on his own hopes as he would have been in the opposite side of the draw.

And he has welcomed the decision to introduce an extra week's break between the French Open and Wimbledon from 2015.

"It will help guys going into Wimbledon as best prepared as possible," he said.

"I think that is what you want in all sports. You want to make sure when the big events come around that the players have had enough time to prepare properly and can play their best tennis.

"With the extra week, that will help."
