UEFA have ordered Spanish league club Atletico Madrid to play their next two Champions League home matches at least 300 kilometres (186 miles) outside of Madrid following crowd trouble earlier this month against Marseille.
European football's governing body said the punishment could be extended to a third home match should there be further trouble at the club within five years.
The matches concerned are against Liverpool on October 22 and PSV Eindhoven on November 26.
In addition, UEFA said Atletico coach Javier Aguirre would be banned from coaching the side for their next two Champions League ties against Liverpool home and away.
It said this was a punishment for "improper conduct."
Atletico were also fined 150,000 Euros (117,000 pounds) for the improper conduct of supporters and lack of organisation, UEFA said.
The club have until October 17 to appeal the decision.
Police and stewards confronted Marseille fans prior to kick on the October 1 Champions League match which Atletico went on to win 2-1. A number of seats were ripped up and flares set off by the visiting supporters.
