I got told that at Man Utd they make the players rotate round during games at youth level, apparently they were the first academy to stop caring about winning as well, this was all during the 90s they apparently started doing this, the guy who told me was an fa coach educator although I forget his name now, so he is probably pretty credible. I am with you on this Mark, I think being fluid enough to play all over is a great ability to have, I appreciate they seem to be divisive to English fans, but Milner and Carrick to me stand out for this, on the surface they appear to have what some considered limited ability, but have enjoyed careers at successful teams, and are highly rated by club managers.
