"It is going to be pretty tough to get back into the team with the way we are playing just at the moment and it's good to see Nathan Ellington showing the quality we all know he has," Campbell has said.

"I don't want to rush back and I played with the ankle for six months when it wasn't perfect, but I hope to be involved from Man City onwards if at all possible."
