Guthrie has been hopeless out wide, in the past. I wonder whether Pardew will change the formation to a 4-3-3, with Guthrie, Tiote and Cabaye in the middle, and Jonas, Best and Ba up front.
Not sure how well that'd work, and the better alternative would probably be simply putting Marveaux in for Obertan in the usual formation.
This is more than likely to happen.
