Have played it for quite some years myself and at a reasonable level as well. Ofcourse there are enough examples of "dirty" players really hurting and injuring opponents. But most what we see nowadays in professional soccer is not even half as bad as the so-called "attacked" player wants to make us believe.

Look at Rugby; a far much tougher sport than soccer. Ever seen anyone "acting", rolling and whining during a rugby match just like Neymar does?
If that happens I think that the coach takes him out of the match instantly and his teammates wil make a fool of him so bad, that he probably will never show up again.
