Agree, this is mine main criticism. If we signed Cedric as a 'one for the future' type of signing, then surely we needed someone better than Martina who can play there now. Instead, both of them are on the bench and we're playing CB and RB against one of the better teams in the league. Maybe we really thought Clyne was staying and got caught cold when he left, but there was still plenty of time to get someone in.
A lot of our good play from last season came from the full backs and you can tell how much we've missed Bertrand (and Clyne) from both an attacking and defensive perspective so far.
On a separate note, and not knocking him, but I'd be interested to see what Stekelenberg's shot's to save ratio is? Must be on par with Gazzanigga's during his run in the team when Boruc was injured!
