Milos Raonic, who came back from two sets down to defeat David Goffin, 4-6, 3-6, 6-4, 6-4, 6-4, in the fourth round of Wimbledon said that a couple of years ago he might not have won that match.

“Maybe I would have had the mental strength, but I don't know if I would have had the exact same perspective on what I needed to do in those right moments,” said Raonic, who will face Sam Querrey in the quarterfinals. “I think that's probably the general understanding of myself and my game that I have significantly improved on. That helped.”

Raonic has brought on former world No. 1 John McEnroe for the grass-court season. McEnroe, a seven-time Grand Slam champion, won three Wimbledon titles in his illustrious career.

“I think he's just enforcing things,” Raonic said. “He's probably talking to me more about my attitude on court in a different way, let's say, than the other guys I have around me.

"He's telling me to go out there and impose myself more; maybe [not be] necessarily more loud about it, but make sure the other guy knows you're there."

McEnroe has been commentating during the tournament, and he had to leave during the match to fulfill his broadcasting commitments. But Raonic said that McEnroe was still giving him significant attention.

"We've spent quite a bit of time," said Raonic. "I just saw him now because he finished his commentating responsibility for the day. I'm sure he'll be there for practice tomorrow cause we practice quite early, before he has any matches, I believe, to call. So I see him quite a fair bit.”
