I don't nessasairly buy this left sided and right sided centre half thing. Its only been an issue since Adkins said he prefers left footed centre halves playing on the left side so that it is easier to play out from the back. Before them wed never discussed it. I'd rather have two good solid centre halves that can defend properly who are right footed than two average ones (like we have) playing on their favoured foot side. Rio Ferdinand and Vidic are both right footed, doesn't seem to have been a problem for them for the last few seasons.
