AZ supporters storm main stand, where many family West Ham players sit

NOS Football–
Whether they were fans or friends and relatives of West Ham players is not yet entirely clear.
In any case, West Ham players rushed to the stands to intervene. They had many relatives at the scene of the fighting. Players from AZ as well as coach Pascal Jansen and director Robert Eenhorn also tried to prevent worse.
The incident happened immediately after the match ended. AZ lost 1-0 and therefore missed the final. The fans were behind the AZ goal, broke through a fence and sought confrontation.
Apologies
Unicorn was bitter about the incidents and commented to ESPN. “Fortunately, no injuries seem to have occurred. All that remains for me is to apologize and wish West Ham success in the final.”
Jansen also addressed the events. “I didn’t notice it at first. Then I looked obliquely up to the back and saw that there were quite a few blows being dealt. I then turned my gaze directly to my players and staff members and tried to keep them away.”
AZ players Tijjani Reijnders and Pantelis Hatzidiakos also reacted:

It was not the first time this season that things went wrong in a Dutch stadium. “It’s annoying, it doesn’t belong in our stadium. Preferably not in any stadium. I feel shame. People will have experienced anxious moments. You still have to control your emotions, even on a night of defeat.”
Peace returns
Police and stewards were on the scene fairly quickly to prevent further escalation. After about ten minutes, calm returned to the stadium. Other AZ supporters showed their dissatisfaction with the misbehavior of some of their own supporters with whistles.
Last week AZ lost the away game in London 2-1. Relatives of players and members of the AZ technical staff were then besieged in the first half when they cheered at an AZ goal.
Earlier in the day, supporters of AZ and West Ham clashed in the center of Alkmaar. On the Stationsstraat it came to a confrontation.
