I'm old school, look back at the managers in the past and the football they had they teams play, did they use Data? yes times have moved on, but if players are told/expected to adhere to the data put in front of them it can take their individuality and talent out of their game somewhat, not saying that data doesn't help in certain circumstances, but its all your hear these days everything is data driven,
Need to hear the opinions from players recently retired or coming to the end of their playing days.
Just my opinion of course.
