Simon Davies says the team must be ruthless and take chances when they come along against West Ham United on Saturday.
The Hammers have conceded 53 goals in the Premiership this season and only Manchester City have let in more at home. The Welsh midfielder insists the aim must be to increase the home side's unwanted tally.
"They have been in a bad way all season and it is important not to let them off. I am sure they are not the most confident team at home and we've got to go there and not make it easy for them.
"They've got good talent in the squad, but we have got to go there and impose our game on them. We must match them up all over the pitch and believe that we can come out on top.
"It is surprising with the talent they've got in the squad to see them down there, although I can't say I've seen many of their games this season. There must be a reason why they are down there, they seem to be letting in goals a little bit too easily.
"If we get chances on Saturday we've got to be as ruthless as other teams have been there and put them away."
Meanwhile, Simon admits to being a slightly taken aback at the little bit of flak he has received over the penalty incident against Fulham on Monday night. Simon was felled by keeper Maik Taylor when clean through and the Northern Ireland international was red carded.
"I thought I was going to score and I was gutted that I got bought down, to be honest.
"He definitely took me out from just below my hip and I could not stay on my feet. If I could have I would have gone on and scored."
