Hopefully Watford was the end of Rondon starting, with Richarlison through the middle you'd have to say Gray and Townsend get the nod ahead of Gordon atm, despite Gordon's decent showings in recent games.
Unless, however, Benitez sticks with Gray off the striker then we can accommodate Richarlison, Townsend, Gray and Gordon. The problem with that is that we keep our current soggy-weatabix-like midfield 2 and our only wide option off the bench is then Iwobi.
4-3-3 for me, Gordon as an impact player off the bench or rotated with one of the wingers when the winter schedule kicks in.
