Minor violence broke out at a fan zone in central Athens immediately after the final, which Milan won 2-1 on two goals from striker Filippo Inzaghi. One woman was slightly injured.
Early Wednesday, two Liverpool fans were injured in a fight.
The arrests included 216 Britons, nine Italians, two Serbians, one Bulgarian, one German and one Norwegian man.
Two people from Norway paid £4,000 for ticket packages but couldn’t get in.
A BRITISH tout is due in an Athens court today charged with trying to sell £40,000 worth of fake tickets.
Merseyside police said 63 people had been prevented from traveling to Greece under banning orders which require fans to turn in their passports and appear at a police station on the day of the match.
But Greek police officers, speaking on customary condition of anonymity, said authorities were due to monitor a group of about 100 Liverpool fans believed to be potentially dangerous.
