"No player should ever feel the need to take matters into his own hands, as Muntari clearly felt obliged to do, by abandoning the match or taking spectators to task for inappropriate behaviour".
"The referee should not just stay on the field and blow the whistle, he must do everything.
Professional footballers should expect to be adequately protected by the relevant authorities", the statement concluded. "He should also listen out for that kind of thing and set an example".
