I quite like the idea of 3 at the back.
Jagielka, Williams and Funes Mori with the likes of Galloway and Holgate as back up.
Enables Coleman and Baines to get forward more too.
GK
Jagielka Williams Funes Mori
Coleman Gueye Baines
Mirallas Barkley Bolasie
Lukaku
It will be Williams - kone - jags/ mori if it's a back 3.
