Cape Town - Seven-time grand slam champion John McEnroe believes that Roland Garros runner-up Andy Murray should think about rehiring former coach Ivan Lendl ahead of Wimbledon, which starts on June 27.The American made the comments in an interview with the Daily Telegraph, saying that his former rival Lendl made a positive difference to Murray with the Brit winning the 2012 U.S. Open, 2012 Olympic gold and the 2013 Wimbledon title while under Lendl's guidance.Lendl and Murray parted ways in March 2014 and the world number two then was coached by Amelie Mauresmo until the two parted ways before this year’s French Open. While being coached by Mauresmo, Murray failed to add to his two grand slam singles titles."I think clearly my old rival Ivan Lendl made a positive difference with Andy," McEnroe said."I am not sure if the baggage that took place when they broke up... I don't know if that was really mutual or if it was Andy or Ivan. I don't know if it is like going back out with your ex-wife or ex-girlfriend."But it would not surprise me and it might even make sense. It might not work. But it is an interesting thought."Murray is currently being assisted by Jamie Delgado, who is part of his coaching team.On the ATP tour, there are a number of players that use former players as coaches for the big events. An example of this is world number one Novak Djokovic, who works with six-time major winner Boris Becker. Japanese star Kei Nishikori has former French Open champion Michael Chang in his corner while Canadian Milos Raonic will be using McEnroe to help him at Wimbledon this year."It's been a win-win for Boris and Novak," McEnroe said of Djokovic's setup with Becker.McEnroe added that if ever approached he would love to work with Murray due to him being extremely professional and a very good player."Andy is extremely professional. He won a couple of majors. So you're talking about the cream of the crop," he said."When you look at someone who's that good, you're always interested... (but) I don't recall ever getting a call. There was never any discussion."
