John McEnroe tells The Independent that he likes how No.2 Andy Murray is showing less negativity on court.
"It's one thing if you turn negative emotion into better playing," McEnroe said. "It's another if you express negativity and your level of play drops. It was pretty clear that was happening with him. Murray's first step was the right one: Try to clean up that part and get away from that, not being so negative. That has helped him. He does probably, I suspect, need a way to express himself and get some of this stuff out. If he could do it and be more positive about it, that would be incredible.”
McEnroe says if the British No. 1 continues to play with positive emotion, the crowd will get behind him even more at Wimbledon.
"When the crowd started to really get behind Murray at the Olympics, that made a big difference. In a way it sort of bothered and annoyed [Roger] Federer [in the final] because as far as I know he had never experienced people actually being against him,” McEnroe said. “That benefited Murray. At first he wasn't doing a whole lot. But eventually he pumped his fist and jumped around a bit. Personally, that was great to see. When you win an Olympic gold medal, you want people to jump for joy. And I do think it helped him to win the U.S. Open."
