“Roger [Federer] looks great —  he’s looked the best of all the top guys this summer,” McEnroe said.   " Novak had an incredible run at Wimbledon and it seems to me he is waiting for the Open.

“I don’t think it matters a whole lot what’s happened with his results in the summer. To me, he’s still the favorite going in.”

Draw for the tournament was announced Thursday.

“There’s a cast of other characters that will want to break through and finally put their names in the record books, and the most obvious ones are [Grigor] Dimitrov and [Milos] Raonic,” McEnroe said, “but Djokovic is still the favorite.”
