This is what Adams' is quoted as saying:
No disrespect to Arsene, but George’s coaching ability, defensive structure and technical ability, for me, is far better.
Well, no disrespect to Arsenal's most successful captain but is anyone going to say that George Graham's Arsenal sides were technically superior to Arsene Wenger's? When it comes to defensive structure, yes Graham's teams were better but they were also simpler: ball there, kick ball away; opponent in the way, apologise after kicking him.
Let's be honest, Wenger has developed the Arsenal football style way beyond anything players like Adams could have played. It is much more of a European/World style.
Graham's was a simpler system for a simpler (British) league in which Admas and co thrived. I will go out on a limb here and say that if Adams was CB now, he would NOT be signed by Arsenal because he does not have the technical ability to survive. [The same could be said for some of Arsenal's current defenders, I know.]
As I said earlier, and will repeat here, my intent was not to prove that Wenger's defence is better than Graham's, I wanted to show that Graham's defence was not as good as some have made it out to be.
Right now, everyone knows and accepts that Arsenal's defence needs to be strengthened. The fundamental question is whether the players coming in should be Adam's like (technically limited, kick first, Stoke-like) or Vermaelen like (technically skilled, pass first, World/European)?
