Ajax have been fined €25,000 and the club’s hardcore fans have been banned from the next home game as punishment for the abandonment of the match against Feyenoord on September 24.

The KNVB ordered the Eredivisie’s bottom side to leave sections 125 to 129 of the Johan Cruyff Arena empty for the match against Vitesse Arnhem on November 25.

The area is usually reserved for Ajax’s most fanatical supporters, known as the F-side, who have a history of violence and hooliganism.

“In determining the punishment we have taken account of the nature and severity of the crimes as well as Ajax’s previous record of sanctions, which contains several violations,” the KNVB said in a statement.

The Klassieker against Feyenoord was abandoned in the 55th minute, with the Rotterdam club leading 3-0, after fans repeatedly threw objects, including flares and plastic cups, onto the pitch. Feyenoord went on to win 4-0 when the match was completed in an empty stadium three days later.

The rules were tightened last season after Ajax midfielder Davy Klaassen was hit on the head by a cigarette lighter thrown from the crowd during a Dutch Cup match between the same two clubs in Feyenoord’s De Kuip stadium.

Ajax currently stand bottom of the Eredivisie but will hope to climb up the table on Thursday when they play Volendam at home – a match that was postponed to make room for the unfinished match against Feyenoord.
