"Adam is on fire this season. He's scoring the goals and playing really well," Butterfield told The Star.
"He did it in pre-season as well and he has managed to carry his form through.
"Hopefully he'll keep scoring and keep playing well. I think he could be a Premier player. He's still young, but he seems to be getting better and better.
"I wish him all the best. Hopefully he can fulfil his potential. I don't see why he can't make that step."
