West Ham captain Kevin Nolan is hoping his side's trip to face West Brom has come at a good time, with the Baggies currently struggling for form.
Both clubs have had good starts to their respective Barclays Premier League seasons but West Brom have lost three league games in a row heading into the clash.
"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."
As well as playing Chelsea and Liverpool, West Ham have also faced Manchester United, Tottenham, Newcastle and champions Manchester City in the past few weeks.
A mixed bag of results has left Sam Allardyce's side in 11th place in the table, but Nolan is pleased with the form the team have been showing despite an ever-increasing injury list.
"We have just come out of what was a tricky schedule of games for us," he said.
"We break the games down into eight-game slots with targets and we have met them both so far.
"It is now about starting another little mini-league, with new targets for another eight games and looking to achieve them again.
"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.
"I just think, with us all mucking in together, we can get through times when we have a few injuries or whatever."
