Club statement Ajax - FC Groningen
Ajax considers what happened in the stadium this evening to be utterly outrageous. We offer our apologies to everyone who has been affected in any way. The safety of spectators and players has been put at risk. That is unacceptable. We emphatically distance ourselves from this misconduct. Fireworks do not belong in the stadium.
