Good post mate, one of our deficiencies this season has been loosing the midfield battle against bigger and more physically imposing midfields. I think teams have cottoned on to us. We have an excellent creative midfielder, in Gomes what we lack and were he suffers is not loosing the midfield battle and being denied possession and in transition through the midfield as a result and or the ball gets to him in slow or impossible positions.
I wouldnt be opposed to playing a double pivot in some games, not all though:
Pickford,
Coleman, Keane, Mina, Dinge
McCarthy Gana
Gomes
Gylfi, Bernard,
Richalson
Or a combo of whever you lie in the advanced positions.
Games i am thinking of are ones where we got out grocked in midfield, Newcastle, WHU and Watford. 4-3-3 or 4-2-1-2-1 depending on how you want to look at it.
