Oxley
Brown New CB Tarkowski Grounds
Smith Mellor
Baxter Montano
Millar
Rooney
Personally, I thought Baxter impressed in short spells on the wing last season, got a good cross on him and can provide to Rooney in the middle. JCH could also be incorporated into that team, Swapping with Rooney or having a switch of the midfield. As LJ said, there is so many combinations.
(Should a new CB not come in, i'd put Byrne in at back)
