it has been building up since two years back, ryadi now are doing the darabni w baka sab2ni w chtaka, only lately have ryadi implemented stricter regulations on who enters their stadium because they risked being banned, we all remember the black flags with islamic versis on them, the chants, the tauntings.... religion was first brought into the game by ryadi, trouble making was first brought into the game by ryadi(of course you would find some riots here and there over the past 20 years), disrupting games when losing on home ground was first brought by ryadi, in faireness they cleaned up their act, but still even then last game a supporter almost assulted a player, hekmeh croud failed in being a role model instead they wanted to go a step above ryadi, so now they lost points against ryadi moraly
