It was quite starkly different from our systems before. It was a definitely
Ndombele-------------Sissoko
-------------Winks
Then:
White-------------Eriksen
---------Skipp
Eriksen and Alli are blessed with workrate and creativity to play either that CM in a 3 role, or one of the front 3. Lo Celso looks that way too. I'm not sure anything other that being ACM in a 4-2-3-1 would suit Fernandes though?
I dont know Fernandes well enough to say with any authority, but he does look best suited to that ACM role to me.
Point being, I think it would be rather foolish to look at a preseason game and decide thats how we will be playing all season, and use that to contextualise how you are viewing players etc.
We know very well that Poch will change things up constantly. We often play 3 or 4 formations within a game, let alone across fixtures.
So ultimately, options and depth are key. Versatile players like Lo Celso, Dier, Winks etc make it happen.
There is definitely room for Fernandes AND Lo Celso, IMO.
I see it the other way round, Lo Celso is more the Eriksen replacement and Fernandes is a more attacking midfielder option rather than the "playmaker"
As Ive said, Im far from expert on him. What Ive seen puts Fernandes in very similar positions as Eriksen, doing a very similar job (albeit not in the same style). Creating and scoring goals, dictating attacking play, occupying the space between the lines behind the striker...
Lo Celso did a lot of that last season, but also worked as more of a CM as well.
