In seasons past Arsenal have been stereotyped, not without reason, as defensively fragile and naive. Arsene Wenger has sought to address that this season with the signings of two new centre backs, Laurent Koscielny and Sebastien Squillaci after a clear out of the defensive deadwood within the squad.
Against Bolton the back four was totally untested, consisting of Gibbs, Koscielny, Squillaci and Eboue. Last season the equivalent rotation would have left Arsenal with players like Silvestre at the back, players who never inspired confidence at the best of times.
Koscielny made only his third appearance for the club, whilst Squillaci made his debut, and apart from one obvious error from Koscielny they coped well with the threat of the physical Kevin Davies, Lee and Elmander.
