Perhaps more of a 4-1-2-3, with Dier being the DM, N'dombele and Lo Celso being the 2 with Winks covering all 3.The problem with 4231 is that it revovles around Eriksen, and Eriksen is on the way out. IMO we won't bring in a comparable player (and Lo Celso is a CM for me), so we therefore have to adopt a different system. With the depth we now have in CM and the (hopefully) far greater creativity from deeper, I can see us moving to 433 with Dier in the middle but dropping into a back 3 when we're attacking. It's tailor made for Sessegnon, Lo Celso and Ndombele.
