Daz to repeat… Arteta uses the money he spends, on the field. If you just take how much money we spend on our players and look at it against our minutes, the most coatly people are on the field.
Contrast with many of the other big teams (bar Liverpool) where large transfer fees and wages are on the bench/loan.
Again, I look at the whole, versus individuals. In any team of 20+ players I can find any exception. I can say for example, Arteta has a young squad, but he plays Jorginhno a lot. Not sure how much clearer I can be. You cannot judge performance on individual things - it’s really bad stats and preference management.
