Wenger was a revolutionary in his early years and he’s one of the managers that changed football completely.
Then he went senile and completely lost the ability to evolve. He was the master of his own downfall in my eyes and he had the delusions that he could turn a turd into gold because he’d made some shrewd signings previously. Wenger aged like milk not wine.
He also actually hugely benefitted from the solid core arsenal had when he arrived; Adam’s, Dixon, keown, winterburn, bould. When they started retiring he lost the plot. Could not sign a defender for all the money in the world.
