Owen Coyle believes Queens Park Rangers' recent results sums up the competitive nature of the Championship.
Since Rovers defeated Rangers in the FA Cup four weeks ago, Ian Holloway's side have defeated Reading and drawn with Newcastle and Fulham, but were beaten by Burton Albion.
But with QPR more active than most in the January transfer window, the Rovers boss doesn't expect to be facing a similar side to the one they beat at the beginning of last month.
"Their recent results sum up the Championship in that everyone would have thought they'd be big favourites at home to Burton Albion last week when they lost," Coyle told Rovers PlayerHD.
"And then during the week everybody would have felt that having lost at home to Burton, going to Newcastle and losing a goal in the first minute, that it would be a comfortable win for Newcastle, yet it finishes 2-2.
"So we've got to make sure that we expect the best Queens Park Rangers team to turn up and that is the one that we have got to be ready to match. If we do that and get to our best then we know that we have shown that we can win those games.
"It will be a test, they have got some very good players, they've spent a lot of money on their squad, so we've got to be ready for the challenge that presents itself."
