It's really hard to pick a suitable line-up mainly because of the midfield problem, but for me one thing is for sure; we need to play the players that deserve to be in the line-up and those who don't should be benched. Anyway, the best line up that I can think of is this:
Reina
Johnson Skrtel Agger Enrique
Kuyt Henderson Adam Maxi
Suarez Bellamy
We also might play Shelvey instead of Kuyt and play Hendo as a winger, but I wouldn't agree on that because Henderson is nothing else but a central midfielder and that's where we should play him. My biggest worry is that we don't have a DM, but QPR are a mid or even bottom table club, we shouldn't need a DM for those games, right?
