West Ham captain Kevin Nolan hopes that West Brom's recent poor form will continue at The Hawthorns on Sunday.
Steve Clarke's side were the big surprise of the season as they stormed to third in the Premier League with four wins in a row last month.
But the Baggies have since lost their last three matches, and Nolan believes his side have a great chance to atone for last week's defeat to Liverpool.
"We are really looking forward to going there and matching them, because they are a fantastic side," he said.
"We hope that their bubble has burst a bit and we can go there on Sunday and get a result.
"They will be a tough side to come up against, I don't think I have ever been involved in an easy game at The Hawthorns, but we go there with confidence.
"We have just come out of what was a tricky schedule of games for us. We break the games down into eight-game slots with targets and we have met them both so far.
"We have a few injuries but it is about us all pulling together even more and sticking close and working hard for each other and the team."
