Andy won't be changing his ways - but he won't be swearing in front of Gran

Ready for action: Andy Murray warms up for Wimbledon

‘I’ve seen videos of myself when I first played at Wimbledon and I’m jumping all over the place and I actually think I’m a little bit different now, a bit more laid-back. You don’t want to force people to get behind you because if they want to, they will. Every time I’ve played here it has been awesome.’

Murray has recounted how he once upset his beloved English grandmother Shirley, from Newcastle, with his behaviour as a junior. As she is visiting Wimbledon this year, he suggested he will be keeping his language clean.

'I was 13 or 14 and I don’t think I’ve embarrassed her too many times since. She’s probably coming down to watch so I won’t be doing too much swearing.’

Murray opens his campaign tomorrow against French veteran Fabrice Santoro, while Roger Federer begins his title defence today against Dominik Hrbaty on Centre Court.

Although Murray is way behind Federer, Rafael Nadal and Novak Djokovic in the betting, not to mention Andy Roddick, he believes it is possible to win the tournament.

‘I think I can do it. I haven’t felt any more pressure than I have done in the past,’ said the Scot. ‘I’ve played very well in practice this past week and I think I’m well prepared so I have a lot to look forward to.’

Murray struggled to keep his feet at Queen’s last week and has changed his footwear from adidas to Nike to try to make sure there is no repeat of the falls that damaged his thumb and caused him to pull out of his quarter-final.

As he has no footwear contract he is free to wear what he wants and hopes the extra dimples built around the sides of the Nike shoe will give him more stability.

Murray, currently ranked 11th in the world, has yet to go past the last 16 in a major, but with a decent draw he feels he is capable of improving on that.

‘I don’t think reaching the fourth round of a Slam is a great achievement,’ he said. ‘Winning a few rounds is good but I want to do better than that. I felt I was building up to a big Slam when I had my wrist injury last year and had some tough matches when I lost in Australia and at the French this year.

‘In Australia there were some things that needed to get better and now I feel I can do well at a Slam.

‘When Roger Federer was 21, he had not won any Grand Slams and was just outside the top 10 and people were saying similar things about him — “when is he going to do this? Why has he not done that already?” Some people take a bit longer to develop.

‘I have a different style to guys like Nadal and Djokovic, who play from the baseline and it is a bit easier to learn how to play their style. Trying different things takes time to get used to.

‘I think I’m getting there, it has just not been as fast as some of the other guys.’
