Zat Knight believes Bolton will reap the reward if they can turn West Ham's supporters against their own team.
The Trotters travel to Upton Park hoping to register their third successive Barclays Premier League victory in east London.
Avram Grant's West Ham crashed to a 3-0 defeat at Aston Villa last Saturday and Knight knows their fans will grow restless if they struggle again.
"The crowd will get behind them but their fans demand a lot," Knight told Bolton's official website. "If we can play our type of football, press them and get them on the back foot, then hopefully we can make the crowd turn.
"Maybe then one or two their players' heads will drop and we can capitalise by getting one or two goals. West Ham will obviously want to do better than they did last week as they made a poor start against Villa.
"For us we want to do better than our draw against last weekend and I don't see why we can't come away with the points we want. Although we believe it was a good performance against Fulham you always want to better yourself. If we do that against West Ham then we believe we'll come out on top."
