Much is being written today about Arsenal and their win against Dortmund. Much is being written about the rearguard, about Arsene finally replacing the famous old guard. Praise is being dished out left right and centre, talk of the 'Best centre back pairing in the PL' and of their coming of age. Those who are lauding the 'big #$%$ german' and Koscielny today, poured scorn on those very same players in times gone past. the supposed new qualities of these players will no doubt be accredited to Steve Boulds coaching, and in part that is of course warranted.
I however believe that Mertesaker has always been quality and that Kosc has always fought like a lion. The difference for me is that the backline is enjoying an injury free run. In times gone by the backline changed almost weekly. It was in such times that those in the know spoke of how poor the Arsenal defence was. When 4th choice CBs were being played in an unfamiliar line up whilst first choice CBs were having to be played at left back.
The famous old rear guard of Arsenal also enjoyed long periods,injury free, so much so that every football fan in the country could name the defensive line up of Arsenal. Long may Sagna, and Mertesaker and Koscielny and Gibbs enjoy their good health.
