Id be tempted to play a 433 with this rumoured team (with Gylfi in a free role) Would mean that Coleman and Digne would have to work for their wages and Gana/Besic would have to cover a lot of ground):
.....................Pickford.....................
Coleman....Mina....Zouma....Digne
.................Gana...Besic..................
.......................Gylfi..........................
Walcott..........Tosun..........Bernard
Edit: Left out Richarlison, not on purpose, just spoilt for choice for once. Where the hell would he fit in? He probably wouldn't, so scratch my 433 unless he could replace Besic but that would leave us vulnerable at the back.
