That it's much better than grassroots!!
Where ever I've seen academy football, the set up is usually very good. The players are usually better behaved, and if not, remind them that they are there to play football, especially at academy level, so concentrate more on the football etc etc. The football is obviously of a higher standard, and so I find there are less fouls, and that if there are, they would rather have an advantage, or take a quick free kick, unless near the box. I also try and play advantage if the balls with the back four, because the coaches usually want them to try and play out of it.
I enjoy the academy games more than grassroots football. Just go out and enjoy it!
