Tennis legend Martina Navratilova says Britain's Andy Murray needs a change in attitude to win a first Grand Slam title.
Murray has failed to win a set in his three major final appearances so far, most recently losing to Novak Djokovic in this year's Australian Open final.
Navratilova, an 18-time Grand Slam singles champion, says he's got the talent but he's got to get tougher mentally.
She says each year without a Slam it gets more difficult, the expectations and the pressure get higher.
Murray has slipped to number five in the world rankings and has struggled for form since his 6-4 6-2 6-3 defeat by Djokovic in Melbourne.
Navratilova says Murray is too quick to pass the blame, looking at his box and yelling at them as if it's somehow their fault he missed that forehand.
She says she would have thought he would have won a slam by now, though he still has plenty of time on his side.
Murray is playing the Miami Open this week.
