Australian teenager Bernard Tomic says it's possible he may take another coach outside of his father John someday. The 18-year-old extended No. 2 Novak Djokovic to four sets in a 6-2, 3-6, 6-3, 7-5 loss in the quarterfinals of Wimbledon. John Tomic has trained his son since he’s been a child and at times has come under criticism in Australia for being a bit out of control, but Bernard has stuck by him.

"As soon as I have done well and made myself the best of a player as I am, then I think my dad can slip out,” Tomic told reporters. "But until then, he's the one that's coached me and helped me out and made me the player who I am now. In time obviously it's going to be like that. But until I become as best of a player as I am, which I think only he can help me until then, it could be one year away or four years away. I don't know."
