West Ham boss David Moyes is wary facing Wolves on Sunday.
Moyes says Gary O'Neil is doing a good job at Molineux.
He stated: "Gary O'Neil has done a great job, and did a good job at Bournemouth as well. Young coaches need these opportunities and I think he's doing a really good job. He's got Wolves looking very steady but we've got our job to do.
"Wolves have always been a good side - good teams with good players. They've had some very experienced managers but I also think Gary has come in and done a good job. There are obviously differences, but they're doing well."
Moyes added: "I don't think there is enough time between games, but does that mean I'm going to rotate loads? I don't know yet. It depends on how the players are doing, their energy levels, and how we feel the lads are doing in the games. This time of year comes with a heavy work load for all teams."
