Despite his superb form, Tottenham midfielder Scott Parker says he hasn't been playing on all cylinders.

Parker, who moved to White Hart Lane from West Ham during the summer, admits the earlier uncertainty over his future is a factor in his current fitness levels.

He said: "I've been struggling with cramp recently to be fair. I didn't have a good pre-season. It was all up in the air where I was going to be.

"I just think maybe not having the pre-season behind me means I will struggle during the late part of games."
