The London club are six points adrift of safety with 17 points from 23 games but signed Jermaine Jenas, Andros Townsend, Yoon Suk-Young and Chris Samba on deadline day to bolster their ranks.

"If you analyse it, we haven't spent that much money on transfers and as for our wage bill, when I look at other clubs when they put their results out, then ours is not too bad and there is now value in the squad," he told the Daily Telegraph.
"I don't think there is any recklessness there.

"It's not always about money. QPR are the bottom club and you don't come to the bottom club for the dollar sign. And I'm not going to get players for the dollar signs."
