"I think for the moment Eden wants to do more," said Wilmots. "He can do a lot for us, everyone knows that.
"Now I'm waiting to see it. It's not a question of putting pressure on him as I know he's under a lot of pressure."
Wilmots added: "I'm waiting for him to take hold of a match and impose himself, even if he's still young to be doing that."
