I'm not sure you can equate footballing intelligence with how erudite somebody is. Rooney and Messi were / are both incredibly intelligent players, and they come across as cretins.Footballers on a whole are not the smartest in the book. Harry Kane seems really simple from that recent documentary. Footballers do what their manager tells them. That's why your Pirlo's, Scholes, Xavi are such a rare breed because they actually had brains.
