The problem with that is that he'd be in the pocket of space that Cunha likes to pick the ball up in. The thing about formations and positions is that there are good arguments for playing loads of different ways, but it's all subjective and impossible to prove one way or the other in terms of how successful it would be. At the moment the formation that we play allows for us to have Cunha, Mbeumo, Amad, Sesko (or Mount/Zirkzee), and Bruno all on the pitch at the same time. If that really clicks then it could be devastating. Sesko is obviously a work in progress and Cunha has been slightly patchy, but I can see what he is trying to do there. If all of those players are playing to the best of their abilities - and particularly when we have a proper press-resistant dynamic midfielder - then oppo midfields are going to be dragged all over the place. Then with the defensive wingback holding a defensive line and one of the CBs stepping up there is the makings of quite an exciting way of playing. We're not there yet in terms of executing it properly, but there is progress and I am seeing flashes of how it could look when all the cogs are working together.
One mental exercise I do is to imagine the same team in a different formation. The numbers (3-4-3, 4-4-2 etc.) have some meaning but through out the game, there are many many different set ups we employ. Most of the time, every side in the league employs a 3-2 base or in more aggressive cases (like with Ten Hag or Slot), a 3-1 base. We do as well. If you assume then that most sides by and large line up in similar ways when they attack then profiling the midfield becomes fairly straight forward comparison exercise. So first, imagine our side in a 4-4-2 to make it easier for ourselves:
------------------------------- GK ----------------------------
--- Yoro -- De Ligt -- LCB -- Dorgu / Dalot ---
-------------- Casemiro -- Bruno ----------------------
---- Amad ----------------------------- Cunha ----------
------------------ Mbeumo -- Sesko -------------------
The City (Chelsea) answer to this is a big / positional beast like Rodri (Caicedo) who can mop everything up and also run play through, paired with a Gundogan or Reijnders or an Enzo.
The Arsenal / Villa answer to this is a playmaker (Jorginho / Zubi / Tielemans) and a physical beast that can bring ball carrying, ball striking and duel winning like Rice (Onana).
I think the Arsenal answer differs from Chelsea / City because profiles like Rodri or Caicedo are so hard to find. It's much easier to find a little playmaker (see the Stiller links) to run your play through from deep and an aggressive ball carrier.
So all that said, if we wan to run Bruno like City ran Gundogan, we need a Rodri type signing. This is easier said than done and none of our links so far suggest that this is the type of midfielder we're looking for. If we think Bruno is our Paul Scholes / Pirlo reincarnation and will be pulling strings from midfield even when he's 38, then we need a Rice or Kante type profile.
So far the indications are the latter. My personal preference is:
(1) Sack Amorim, move to a 4-2-3-1, Bruno to #10 and sign two new CMs.
(2) Keep Amorim, sell Bruno and sign two new mids.
