I would go 4-3-3
Guzan
Hutton. Richards. Clark. Amavi
Westwood.sanchez.gueye.
Adama. Grealish
Gestede
That is also the line up I would start with.
I like that too. Only possible change I would consider would be to put Sanchez and Gueye as our defensive midfielders, bring in Veretout to allow him to play to his strengths in the more advanced midfield role and obviously dropping Westwood.
Defensively we'd be more solid, strong in midfield and in attack we'd threaten left, right and centre.
