Mark Warburton has so far masterminded a positive QPR start to the season, and a three-game win streak.

In the last three fixtures, he has swapped to five at the back - a system that has provided Rangers with eight goals in three games.

However, with the problematic issue of heading to Millwall on Saturday, Warburton could be tempted to make a couple of changes so that his side has the mixture of experience and talent to come away with three points.

Here, we take a look at TWO tweaks that could be made...

Cameron replaces Ball

Geoff Cameron is a dominant and experienced force at the heart of QPR's midfield. The 34-year-old could be recalled upon for the test at the Den to help QPR's youthful midfield pairing of Ilias Chair and Eberechi Eze.

His experience was missed against Luton Town when the Hatters gained a foothold in the contest and looked as-if they were going to complete the 3-0 comeback. In addition, his vision as a deep-lying play-maker is a underrated trait of Cameron, who's vision excelled in Rangers' opening day victory at Stoke, and their defeat to Swansea.

With this in mind, switching Dominic Ball for the commanding midfielder would prove to be a wise choice to make.

First league start for Pugh 

Marc Pugh has been used consistently off the bench so far, but likewise with the characteristics Cameron offers, Pugh could be a wise player to start. He possesses the experience to guide the team through what will-be a hostile atmosphere. In addition to this, he has a creative spark and the skill to help his team on the opposite end of the pitch.

Pugh showed he could fill in as a central midfielder in the final 20 minutes against Luton, so swapping Chair for Pugh could happen. However, this will hurt QPR's attack nonetheless due to the exceptional partnership Chair and Eze have formed.

In whatever way Warburton may choose to change his team, Cameron for Ball looks far more likely, although Warburton must be wary of the impact the crowd could have on his young midfielder.
