The formations will undoubtedly be fluid though. Players form what I have seen and read, and I get can change, is that Ange teams expect players to change dependant on with or without ball, the inverted FBs stuff etc. I think you will see players in midfield being a 2 when needed to be deep and then a one with the ball with one of them moving more advanced. Thankfully with say Benta and Bissi you have two players who are good on the ball and equally able to sit deeper, so I think that works well, Maddison can also pick the ball up deeper so a three of them can work in more than one way, which is what we need IMO
I’d be very happy to see that kind of movement and rotation - felt like it was so lacking under Conte!
