Similar to the reaction by Federer after being up 5-2 at the FO and the drop shot miss. This is why Nadal wins slams, because of his mental toughness. He never gives up no matter how bad a mistake he makes. Others do.
Get Murray off the court, what a pathetic display of tennis. After dictating for a set and a couple of games, his entire game goes downhill and for what? One forehand . Kudos for Nadal for maintaining composure but that was just such an utter collapse by Murray
