Actually much harder than I thought. I wanted to take the Ox but there was no room, and the likes of Milner and Carrick would be decent utility/ back-up options but there's a lot of competition in that midfield. The forwards pick themselves though - Theo doesn't deserve to go.
My starting XI would be:
Hart
Clyne - Smalling - Cahill - Bertrand
Dier - Wilshere
Sterling - Alli - Welbeck
Kane
Clyne - Smalling - Cahill - Bertrand
Dier - Wilshere
Sterling - Alli - Welbeck
Kane
