Queens Park Rangers have received mixed reviews this season.

One of the league's best attacking sides is also one of the worst defensively - QPR have so far netted 51 goals this season, more than both Leeds United and Fulham, but have conceded as many as bottom-club Barnsley.

In the circumstances though, many fans feel that Mark Warburton is doing a fine job: A host of new players coming in over the summer, many of whom are young and promising, and having to deal with the loss of top-scorer Nahki Wells which could still scupper QPR's season.

Relegation seems a far-off concern after the weekend win over Stoke City, but QPR could quite easily slip into a relegation scrap with all of the bottom-three, Wigan, Luton and Barnsley picking up unexpected wins of late.

Here we take a look at three mistakes that QPR and Warburton can't afford to make in the season run-in:

Reverting to a back-five

Having stuck with a back-four now for so long, it's unlikely that Warburton will revert to the back-five that they started the season with. With three-centre backs on the pitch and two attacking-minded full-backs, it made QPR wholly exposed.

They weren't the fastest of centre-backs either, and this was a time when QPR were shipping goals for fun. A back-four provides much more defensively stability though.

It allows for the attacking players to do their thing, and for the back-four to stay as just that, often with two midfielders sitting in front of them - all of QPR's four clean-sheets this season have come since the switch to a back-four.

Changing goalkeepers

With Liam Kelly and Joe Lumley have been sharing to no.1 spot all season, it looks like the former now has it on lock-down. Lumley started the campaign in-goal but was dropped after some shoddy performances, then Kelly was brought in and he was injured, then Lumley again and back to Kelly.

All that changing was doing QPR no good. They need to settle on Kelly now as he's shown the more ability this season, and it'll give the defensive set-up confidence knowing that they've got the same head behind them.

Kelly has been steady for QPR, if not spectacular, and has less of a tendency to make the mistakes that Lumley does.

Over-using players

Probably Warburton's biggest challenge after a subdued January transfer window is not over-using his players. QPR look incredibly thin on the ground and a lot of their star players, the likes of Ebere Eze, Ilias Chair, Grant Hall and so on have already played a lot of football this season.

A few legs were looking to tire towards Christmas, and Warburton needs to utilise the players he's got to not risk any unwanted injuries and to keep his players fresh and ready to fight for what could be a tricky end to the campaign.
