Andy Murray faces a tough test when he takes on Xavier Malisse in the second round at Wimbledon.The Belgian reached the semi-finals in 2002 and he was one of Murray's practice partners at Nick Bollettieri's tennis academy in Florida.Murray said: "He's really talented. He had quite a lot of problems with injuries over the last couple of years but I practised quite a lot with him in Bollettieri's."He obviously trains there and has done pretty much all his life. He probably isn't playing as well as he was when he made the semis here but he is a dangerous opponent who can play very well on grass."Malisse insists he will not be intimidated by the noisy support for Murray.He said: "I feel like I'm playing well. Hopefully, I can give him a tough match and come out on top. He has a good defensive game, but I like playing that kind of game."
