John McEnroe tips Laura Robson to follow in Andy Murray's footsteps and win grand slam Robson is now in Florida, working with her new coach Zeljko Krajan to develop her heavy-hitting left-handed game. Her rival and near-contemporary Heather Watson was also at the Albert Hall yesterday, where she joined Tim Henman in a mixed-doubles exhibition. But McEnroe seems less sure about Watson's ability to challenge the very best players. "She's a spirited young girl," he said, "but she's not very tall so that makes it tough. She should idolise David Ferrer - she's got to be a real hustler or battler. She is just going to have to do it the hard way. Heather is around 50 in the world which means she has already done well in a way, considering how difficult it will be for someone of her size. McEnroe had hoped to play Ivan Lendl tonight, in what would have been their first meeting on the ATP Champions Tour. But Lendl withdrew with problems in his knee and hip, which was a disappointment both for his opponent and the tournament. Still, McEnroe considers that Lendl's arrival in Andy Murray's camp almost 12 months ago was a critical factor in Murray's breakthrough season. "Ivan was for sure saying some of the same things that Andy was hearing before - whether it was "You've got to work on your second serve" or "You've got to be more aggressive off your forehand." But for whatever reason, he got into Andy's head and he started to do those things. Andy did have a couple of tough losses at the end of the season, but he was definitely knocking on the door. If he can take that as a positive instead of a negative then you could be looking at a couple of majors next year. But it would be nice if he could look a bit more excited next time he wins one.
