UEFA is to discuss ways to stem unruly fan behavior at its next meeting in June, chief executive Lars-Christer Olsson has revealed.

The possible punishments could include loss of points or a home match ban for teams whose fans misbehave, said Olsson.

The announcement came amid concerns about fan behaviour following the abandonment of last week’s Champions League quarter-final between Inter and Mila. Inter fans threw flares and bottles on the field with one flare striking Milan goalkeeper Dida.

Last month, Swedish referee Anders Frisk announced his retirement after receiving death threats from Chelsea fans after officiating a Champions League match between Barcelona and Chelsea.

“There will be a very clear message about what will be accepted and what will be the consequences of unacceptable behavior,” Olsson said.

UEFA also has the power to ban all teams from a certain country from European competitions, just as it did with English teams in the wake of the Heysel disaster.
