London, July 6(ANI): Andy Murray's coach Ivan Lendl is expected to play a key role if the British number one player is to achieve his lifelong dream of winning a Grand Slam, and create history by becoming the first Brit to win Wimbledon since Fred Perry in 1936.

Murray would need to beat Frenchman Jo-Wilfried Tsonga in the Wimbledon semi-final on Friday if he wants to conquer the All England Club.

If Murray is going to defuse Tsonga, he needs to maintain the intensity he produced in his quarterfinal win over David Ferrer, and this is where he can draw on the experience of his coach and mentor Lendl.

Murray said he meets Lendl the evening before matches to run through the tactical approach for the next day.

Ivan is very exact. He doesn't miss anything. He gives you a lot of information on players, and we have started to have our tactical talk the night before matches so I can sleep on it, The Telegraph quoted Murray, as saying.

That's really been the big difference and it's helped me be more prepared, he added.

Murray also revealed how coach Lendl has made a particular change in his preparation before the match, which is now paying dividends.

I hit a lot less serves than I used to. Ivan thinks you need to rest your shoulder and make sure it is loose, not tired, because over the course of two weeks you hit thousands of serves, Murray said.

That may be a reason why I am serving well deeper into the tournament, he added.

Murray has already notched up a tally of 65 aces in Wimbledon so far, and if he can sneak past Tsonga, this much-improved serve will be his key weapon in the final. (ANI)
