Sweden legend Henrik Larsson has called on fans to put bury hooliganism following the death of a fan ahead of one of Sunday's matches.
The opening day of the Allsvenskan season ended in tragedy after a Djurgarden fan was assaulted en route to Helsingborg's Olympia Stadium.
Local newspaper Helsingborgs Dagblad reported that an unprovoked attack was carried out on the stairs of the medieval Karnan structure, with eyewitnesses claiming the victim was hit on the head with a glass bottle.
The 43-year-old was treated at the scene before he was taken to a local hospital, where he died of head injuries, and the match was abandoned late in the opening half as Djurgarden fans reacted with anger at the death and stormed on to the pitch.
"What the hell are we doing?" Larsson, who has 106 caps for his country, told Swedish station CMore. "I mean, we're supposed to be going to football.
"Now there is a mother and a father sitting at home, crying their eyes out. It's awful. We need to get rid of it from Swedish football."
It is the second time this year a Swedish club has been involved in an altercation with an opposing team after Djurgarden's friendly match against Germany's Union Berlin in January was abandoned because of riots inside the stadium.
That match was initially delayed in the Swedish capital after both sets of fans invaded the pitch, tossing flares across the stadium, before the game ended in the 74th minute.
As of Monday morning, police had not arrested anyone over the death of the 43-year-old.
