I've advocated for the 3 man midfield since Conte started using before he switched to a 352. Makes a huge difference.
Sorry for using your quote in this discussion, this is not because Ive seen you mention this before, but a general notion.
But the thing I hear most in this forum is a debate of '2 man midfield vs 3 man midfield'. We have played most of the season with 3 men in midfield and we have sucked, hard! Playing these 3 midfielders that Allegri prefers, limits us so much, especially the way we play it! Yet people still think it is just a matter of how the formation looks on paper, how many players do we have on the field whos preferred position in FM says 'CM'.
It might change if we get other midfielders but as I see it, it is not really a matter of formations, but more a matter of mindset, general tactics and playing with our best performing players.
I completely agree with @MikeM about our players in midfield not being up to playing at this level at all (Matuidi, Pjanic, Khedira). Why play 3 limited players instead of just 2 then and then use our strengths instead of trying to cover up a huge weakness. Pjanic is my new player to question, after Max seems to have finally realized that Mandzukic, Lichtsteiner (took 2 seasons) and Marchisio were our limitations and should get limited time. Im not sure we can afford to play with Pjanic unless he steps up. He has his skills and passing abilities, but he is also often one of the first ones to give up and fuck up when things are not working. However for now of course he is the strongest we have in mid, together with Bentancur. Bentancur and Khedira played really well together though and I would be interested in seeing that midfield pairing again.
Although headless, Matuidi seems like the most constructive player out of Pjanic and Khedira, as he atleast runs. So it is really a puzzle who to play. Thats why I think we should maximum play 2 of these CM fuckers and then use cover from Cuadrado and/or Bernardeschi on the field (with Bentancur) to simply improve our passing and technical abilities and be more aggressive!
