My wish list would be striker, RB and DCM.
DCM comes in as cover for Souza, I liked the look of Shackleton but he isn't going to be as physically imposing and I don't think there is anyone else for that role specifically
RB- currently I actually see Seriki as the best option. Looks solid defensively and looks positive going forward. Gilchrist's first game looked really solid and I like the look of him but seems to limit our attacking options down that side if we need it. probably is too early to tell.
Striker- We know what we get with Moore. Campbell could be a great signing and got my fingers crossed we can see him soon. Everyone else is unproven, I am including Brewster on this as for all his efforts his excellent track record is now a few years old and he seems like he knows he also has a lot to prove. The youngsters in this position seem a season off being a reliable young option (thinking Osula last year...)
