Scotland's Andy Murray has scoffed at John McEnroe's suggestion that this week's US Tennis Open is his best chance of winning a grand slam.
McEnroe, a former US Open champion, has tipped Murray to win the title and claim his first grand slam title.
McEnroe says Murray's in great form after winning a lead-up event in Cincinnati while his three main rivals, Roger Federer, Rafa Nadal and Novak Djokovic, all have health concerns.
But Murray, who's played in three grand slam finals but lost them all, says McEnroe's comments are unhelpful.
Murray is seeded fourth at Flushing Meadows but is the only player among the top four not to have won a major - although he says that doesn't bother him as much as it used to.
