Mark Warburton insisted that QPR have made progress this season despite conceding that his side would likely need to win their remaining five games in order to reach the play-offs.
A first-half own goal from Jimmy Dunne followed by a Cameron Archer strike condemned Rangers to a seventh defeat in eight games, casting further doubt on the future of the under-pressure Warburton.
QPR have occupied the play-off spots for much of the season but their recent slump has seen the team slip to 10th – six points behind sixth-placed Sheffield United.
But manager Warburton maintained that his side’s play-off challenge this season has shown that the club is moving forward under his management.
“We’ve been top six all season, we come out the top six and suddenly my job is under threat according to everyone in the media,” he said.
“From my point of view I just do my job. I don’t think I can ever be accused of not doing my job with the players, working with them individually and collectively.
“I’m not going to go on the defensive in terms of where our budget is, but we’ve been top six all season.
“We’ve gone 13th, we’ve gone ninth, and we’ve been top six all season. I would say progress is being made.”
Rangers play promotion-chasing Huddersfield and Sheffield United over the next five games and will require a drastic turnaround in form, as well as teams above them dropping points, to be in with a chance of promotion.
Warburton added: “We’ve got to win five games, get 74 points and then see if that’s enough. You hope that should be enough. That’s all we can do.
“Today we had some clear-cut chances and we’ve got to take those chances. It’s as simple as that.
“To give away two goals of that nature and miss the number of chances we missed is beyond frustrating.”
Meanwhile, QPR defender Rob Dickie has been ruled out of the remainder of the season because of a hamstring injury.
