Think you're right Royston, we look a little bit bare now at CB and we're one injury away from having a bit of a disaster in defensive midfield with Matusiwa being the only one who really sits and breaks up play. My feeling is Nunez has been brought in to play the double pivot not the 10.
So, if (once) all fit, what would be our strongest, or preferred 11, and what formation would we like to see. I'd like to to go with a 4-2-1-3 Palmer Furlong O'Shea Greaves Davis Matusiwa Cajuste Nunez (in front of the 2 holding midfielders) Akpom (on left of a 3) Azor (give him a chance, can't do much worse than Hirst) Egili (on the right of a 3). Matusiwa and Cajuste can do the Morsy/Luongo roles, and cover left & right when needed, and Nunez can drop in to cover in CM when either one goes wide. Furlong can cover the CB, if (or when) Davis bombs forward, and Greaves can cover the space Davis leaves.
