Benitez said, "He's getting better, he has been training well during the week. We still we have a couple of training sessions so will see how much he can improve.
"In terms of mentality, yes. In terms of his fitness, it will not be 100% but it's getting better so, I have confidence that maybe he can start and I'm confident that for sure he will give us something."
On Wolves, he added: "They have pace, they have ability, they have a system that they know quite well and they have some good players.
"It will be a quite dangerous, they have been doing well in their last games but they were doing well also in terms of playing and creating chances in their first games.
