It tells you something which is better than using nothing to support your argument.
I remember what I saw and the facts I've highlighted support that view.
Ozil immediately transformed the side on his debut. Our performance against Napoli at home was the best we had played in years post-Fabregas, and Ozil was at the heart of it.
Ozil was the crown jewel of the 13/14 system, allowing Ramsey to move up the pitch, Giroud to come short, Rosicky and Cazorla to cut in from the flank and we had a very centrally focussed heatmap with Ozil key to everything.
I don't even like Ozil like that but bias is clearly a powerful thing.
