IMHiO, Sean gregan is not and has never been a centre-half (in a back four anyway). I know he may play there for Oldham but IMHO he is a defensive midfield player and we should try and play him there if possible (its where he made his name at Preston). He could play as the spare man in a back 3 but i don't think that works very well (see Crewe last season). He is the best passer we have in the team and playing him ten yards further up the pitch means he can play killer balls for Davies and Hughes to run on to. OK he might not be able to run for 90 minutes in midfield but how much running did shez do in his time, if you play him with someone who can run all day it probably won't matter. He is simply not quick enough to play centre-half at this level where a majority of the strikers have a lot more pace than him. This has been our problem this season that Thompson seems slower than Haining (not that Haining was particularly quick) and enough teams have a player that little bit quicker than Thompson (plus a player quicker than Gregan). Plus what i've seen of Trotman he looks reasonable and Stam might play this season if he stops spending all that time injured, so we have 3 other centre halves. However, of our central midfielders only Kilkenny looks close to Wellens, McDonald has been poor ever since he conceeded that goal at Carlisle, I've not been impressed with Kalala, Allot is Allot so i think it'd be best if Gregan was played in midfield as its a matter of strength in depth at key positions, especially with kilkenny out for another 5 weeks.
