Steve McClaren has urged his QPR players to forget Tuesday’s FA Cup win over Portsmouth and focus on beating Birmingham this weekend.

Second-half goals from Nakhi Wells and Matt Smith sent the Rs into the fifth round for the first time since 1997 but they have lost their last three matches in the Championship.

McClaren told he does not want to see complacency set in for the match at Loftus Road as they look to secure survival as quickly as possible.

“We did a professional job and we are into the next round [of the FA Cup], but now we park that,” McLaren said.

“This is a very important game for us.

“What we need to do is take the belief and confidence from Tuesday. When we do things right and do our jobs, we are hard to beat, we keep clean sheets and we win games.

“We have to get back to that in the league.

“It’s important we put the cup excitement to the side. It’s back to league action now and we need to start picking up some points.”

QPR are winless in five league games and risk having their season peter out into mid-table mediocrity.

“There’s a cluster of clubs in the middle of the table who are up and down like yo-yos,” said the QPR boss.

“Consistency is the key. When you get consistency you climb the league. We are capable of doing that, but you have to get a result before you build that consistency.”
