Dinamo Zagreb have been hit with a three-point penalty by UEFA following "serious crowd disturbances" before and during their Europa League game against Timisoara on October 1.

Dinamo, who must also play their next two home games in the competition - against Ajax and Timisoara - behind closed doors, have had their points tally in Group A amended from three to zero.

Trouble flared in Timisoara city centre and at the stadium with over 30 Dinamo supporters arrested. Dinamo won the match 3-0.

The Croatian club can appeal the decision within three days of receiving the written reasoning.
