Steven Naismith says there's more to come from him for Everton.

The 26-year-old former Rangers man believes there is much more to come in 2013.

"Since I've arrived, I have contributed in some ways with a few goals and stuff like that, but definitely the best is yet to come," Naismith told "I'm still getting used to the way the team plays, still getting back to 100 per cent fitness from my bad knee injury and, although I've been involved a lot, I've probably not shown what I'm totally capable of."
