London: Bernard Tomic believes he can return to The All England Club as a title contender after having his European summer resurgence halted by a second-round Wimbledon defeat.

Tomic had his opportunities in a 2-6, 6-3, 7-6 (9-7), 7-5 loss to Japanese ace Kei Nishikori, but paid the price for being unable to convert any of three break-point chances in the pivotal third set.

"I started feeling pretty bad out there. I've just been sick the last week," he said.

"But he's playing well and is a world-class player and this is a slam he hasn't done well - he's only reached the fourth round a couple of times, but I think if he plays good like this he can go deep."
