He can cover for Santi, Oz, Alexis and Feo/Iwobi on the wings.
He's useful from the bench.
But I think AW likes this pacy front 3. And if they keep playing like today, who gets dropped for Rambo?
Yes, in games where he needs to be more conservative, he'll play on the flank.
But as a No.10, he was one of the best players at the Euros. Can't see him happy if he's not starting. He'll prob play him for one of Feo/Iwobi, won't he?
