If he goes full Burnley, I'd say it's this:
-------------------------CalvertLewin------------------------
-------------------------Maupay/Iwobi----------
McNeil-------------------------------------------------Gray
--------------------------Onana--Gueye------------
Mykolenko-Mina/Coady-Tarkowski-Patterson
-------------------------------Pickford------------------
I think it could work. The Prem is better tactically (money for managers in the mid-table) and skill-wise (money for transfers in the mid-table) now, but this looks a decent lineup for Burnley ball, stronger than - but similar stylistically to - the ones that stayed up. Crazy they didn't get a RB, as Coleman looks done and Patterson gets hurt. Mina could be good in this deep line if he stays healthy, I'd go with him as first choice over Coady for the aerial dominance, Coady better passer so can come on in games (rare CB for attacking sub) if they're down or maybe at home against bad teams. Should suit Onana, simple role for a young guy and breaking up play and getting forward vertically are his strengths. Bad fit for Iwobi but if he wants to play a bit more football, him as a 10 or in a deep 4-3-3 with him stepping up to be a 10 at times like Odegaard does defensively is a fair half-measure. Maupay it's a great role for.
