West Ham boss David Moyes is wary facing Sunday's opponents Nottingham Forest.
The Irons meet Forest on the back of last night's Europa League win against Olympiakos.
Moyes said, "Every game is really important and you have to win. We'll have to play well. Nottingham Forest are a decent team and had a good result last week. We've had a couple of tough results, but we beat Arsenal in the cup and won last night.
"Of course the Premier League is important, but we've also had some really good wins in there as well.
"Steve Cooper has done a brilliant job and looks as if he's building on it this year. Steve has brought in a lot of new players as he did last season and he's doing well."
On James Ward-Prowse being ignored by England coach Gareth Southgate, he added: "He's a great lad and has settled in quickly. From my side, I hope he keeps playing well, setting up goals and scoring.
"I think Gareth Southgate has done a great job and he's got a lot of good players to choose from, including James."
