No, there are 4 rules, very basic all, fair play is responsibility of both managers.
Resuming is so simple:
-No 1,2,3 and 9 star players allowed.
-120% AvQ as Max. once match starts.
-3 subs allowed, of 120,0% avq each one max.
-Substitutions are limited to 1 in first half, from the 30'+ and 2 during 2nd half, only in case of injuries, this limit can be broken.
Isn't a big mystery really, easy to manage and keeping a fairness![]()
