Really, so watching and seeing where a player is positioned and (correctly) stating that hes out of position is an "obsession" ?
I'd call it talking football.
On his debut Villa played a box midfield. He was deep next to Tielemans.
We have never played a box midfield since Onana joined. We have also never sat him deep with another midfielder.
So, my point was that we dont use a 6....just two central midfielders with them being used incorrectly e.g typically last two seasons Gana deeper than Onana and wandering out of position chasing the ball.
No issue with having 2 CMs as long as we have the players to fit the system which seem to be Garner and Iroegbunam.
Armstrong seems to be a future 6 ?
