We obviously can't allow Villa all the chances on goal we allowed QPR, Bent is a good poacher, and has good supply, we need to push further up, I'd probably go for

Simp Colo Taylor Santon
Tiote
Obertan Cabaye Marveaux Guti
Best
Think 4-3-3 sacrifices some width, hopefully a 4-1-4-1 will allow us to protect flanks while still not having the same midfield problems as against QPR, of course at expense of attacking threat, but shola didn't convince, can change it up later, and marveau and cabaye should be pretty good in support of Best who is at least on form.
