Look for United to sit back and hit Arsenal on the counter attack at every occasion. When United are on the offenisve the only defender that will tasked to stay put will be Rio, where as Smalling, Jones and Evra will all bomb forward. When United are defending Valencia, Carrick, Scholes and Rooney will drop back to offer help.

Good 11, you've got there. The only thing I might change is to start with Wellbeck instead of Hernandez. Not that anything's wrong with Chicarito, Arsenal have a habit of dissolving under physical pressure. Wellbeck is quite muscular and can throw their back 4 off balance.

Is Welbeck back? I thought he hot injured against Bolton.

Torygraph says he'll be available.
