Andy Murray 'Swears' he is not the Most Foul-Mouthed on Court

Andy Murray admits he can be foul-mouthed on the tennis court, but when it comes to swearing there are a lot worse offenders around than him, he believes.

Murray let fly with a few more expletives in his French Open second round match at Roland Garros on Thursday despite comfortably seeing off Marinko Matosevic of Australia 6-3, 6-1, 6-3.

Asked if he thought it would be a good idea at times for players to have mini microphones attached to their shirts during games, Murray said it could work.

"I think with a lot of the players it would be very interesting," he said.

"I think the players that speak in English everybody picks up on that. But some of the stuff that guys say in other languages is a lot worse than the couple of words that I tend to use on the court.

"There are a few phrases that some of the guys use, and they're not pretty."

Asked who the offenders might be Murray replied: "Some of the ones in Spanish aren't great. Some of the Italian phrases, as well, are not so good. Some of the Serbian phrases also aren't great, either.

"I'm not the only one that talks to myself. I think what I say is fairly mild compared to the guys that speak the other languages that people don't pick up on."

Asked again if he was any nearer to naming a new cach to replace Ivan Lendl and to comment on the latest rumour that former French star Amelie Mauresmo was in the running, Murray gave little away.

"To be honest, ever since I stopped working with Ivan, there has been a lot of different names that people have mentioned," he said.

"Obviously Amelie this week. There was (Mats) Wilander. There has been (Jonas) Bjorkman, John McEnroe, (Martina) Navratilova, Leon Smith, who is the Davis Cup captain, Bob Brett. There has been a lot of people that people have talked about.

"You just have to kind of put up with it. When the time is right I will make an announcement. But nothing to say just yet."

Next up for Murray will be a match against Germany's Philipp Kohlschreiber, who brushed him aside 6-2, 6-1 on clay in Monte Carlo four years ago in the only meeting they have had to date.

"Very, very tough match for me. I played him once before on clay and I think I got three games or something," he said.

"He obviously won a tournament (in Dusseldorf) last week. He's not dropped a set here, I don't think. So, yeah, he will be very tough, very good player."
