Might we start with 3 at the back? I think a back 3 of Mckay, Donaldson and McCart is very solid on paper. From what I've read from QoTS fans, Rooney is very good going forwards but a bit suspect at the back, so a Right Wing Back role might be a shout. This would also free Tremarco to bomb down the left - we all know what an attacking threat he can be.
I liked the look of Oakley and Austin together up front towards the end of the season, so a 3-5-2 is a way of keeping them in the team together again.
Trafford would sit deep when need be, whilst Polworth and Doran would be given a bit more of a license to play further forwards. I've never really liked 3 at the back, but I think for the first time we have 3 good enough CB's to be able to play it. My only concern is that Polworth and Doran are more attack minded players, so it might leave us a bit more open, however, we do have 5 defenders on the pitch so I wonder if that would compensate for it. If we're being cut open a bit, we could always push Doran further forwards, drop one of the strikers and put Chalmers in the middle.
