Australian Marinko Matosevic has questioned Andy Murray's decision to appoint Amelie Mauresmo as part of his new coaching team.
The former world number one was something of a surprise choice from Murray, who had been without a coach since parting company with Ivan Lendl back in March.
The Scot will train with the two-time Grand Slam champion for the first time on Wednesday, but Matosevic admitted that he would not be able to be coached by a woman due to the doubts he has over the quality of the female form of the game.
"Apparently there's a few guys in the top 100 who are coached by women. [Mikhail] Kukushkin is coached by his wife, Denis Istomin by his mum, and she's done a great job with him," Matosevic told reporters.
"For me, I couldn't do it, since I don't think that highly of the women's game. But Andy's mum coached him and she did a great job with him, so we'll see what happens.
"It's all equal rights these days, you've got to be politically correct, so someone's got to give it a go - it won't be me."
Matosevic shocked Marin Cilic to progress into the second round at Queen's today, a tournament of which Murray will begin his defence when he faces Paul-Henri Mathieu tomorrow.
