He told Villa's website: "Everybody's in contention for Saturday. When you've lost a game or two, some players are going to be less confident than others. We have to get back to winning ways. We haven't got the biggest squad in the world, so they're all in contention.
"I think Wayne is starting to slowly regain his confidence. He can deliver. He's got nice feet and a nice turn of pace. He's getting back to the player we know he can be.
"It's definitely a confidence thing. Once you stop going past players, for whatever reason, and maybe someone is telling you to do something different in the game you can find yourself low on confidence.
"All of that will come back once he's regularly beating players and knows he can beat players. Once he gets it in his mind that he can, he'll be fine because that wee turn of pace he has is enough to beat players."
