Unpopular opinion...
I dont think we actually need a midfielder... we just need to play the right system.
None of our DMs are capable of playing the lone 6 ETH wants to play... But very few players are, and I'm not sure Palhinha could either.
But if we went back to a double pivot, which in my eyes is clearly the right system to get the best out of our squad, we actually have decent options when everyone is fit.
Casemiro, Mainoo, Amrabat and Eriksen for the double pivot, and Bruno, Mount and McT for the 10 position.
It's all irrelevant anyway, because there is zero chance ETH is going to change back. I predict him dying on the alter of his 4-1-----4-1 formation by around Feb.
