Does anybody know of any available published or online information about individual match performance data for youth. I am interested to know if anyone is studying or has studied performance statistics such as passing accuracy, etc and how they tend to develop over time with age. Was Xavi 90+% passing accuracy when he was 14? 18? I'm thinking people were not tracking the things at the time. Are professional teams using stats for the youth teams? How about National youth teams? If so how do they compare to professional Big 5 or MLS numbers?
