A handful of West Ham supporters were spotted fending off a wave of AZ Alkmaar ultras, who appeared to have breached the away section, following full-time at the AFAS Stadion on Thursday night. Pablo Fornals booked the Hammers a place in the Europa Conference League final with a composed strike in the dying embers of the tie.
The 27-year-old midfielder replaced Said Benrahma with a quarter-of-an-hour to go and, in the fourth minute of added time, he secured West Ham their first European final since 1976. David Moyes' side returned to east London with a 3-1 aggregate win following their 1-0 victory in the 1-0 semi-final second leg.
But, before the Hammers stepped on the flight home, ugly scenes broke out in the stadium. In response to the brawl which broke out, the Dutch police have confirmed that no arrests have been made yet, as of 10:00 GMT on Friday, 19 May.
