I simply can not understand why you would pay £90mil for Pogba then play him in a 2 man midfield.. especially alongside a liability like Fellaini. You're putting a leash on him. You should get a proper DM in like Schneiderlin, with Pogba and somebody else (Herrera?) ahead. Then you could obviously have two wide men flanking Ibrahimovic, but with your players I'd go with a diamond and have Mkhitriyan playing in behind Ibra and Rashford.
