Everton boss David Moyes is concerned over Darron Gibson's fitness.
Moyes admits managing Gibson's previous knee ligament injury means he cannot play every game.
He explained: "Darron has done well.
"I thought he was good. He is a good passer. And he is a really fit lad.
"But what he has not had is match practice. We are playing quite regular so I have to be careful.
"We are always wary. He picked up a knee ligament injury and we have to careful over playing him."
