UEFA has taken strict action against Legia Warsaw following the violent clashes that occurred in the build-up to their Europa Conference League game at Aston Villa last month.
The Polish club has been banned from having any away supporters at their next five European games.
In addition, they have been fined £86,100 and ordered to pay reparations to Aston Villa for the damage caused at Villa Park.
The clashes involved Legia Warsaw fans and the police, with missiles and flares thrown at officers as supporters were held in a coach park near the ground before they were due to enter the stadium.
West Midlands Police charged 46 men, and four officers were injured.
Although the game started on time, no Legia fans were allowed in ahead of kick-off.
Apart from the violent clashes, Villa stewards had to remove several people believed to be away supporters from the home stands.
Footage on social media also appeared to show objects being thrown into the stadium from outside.
Villa made an official complaint to UEFA regarding the behaviour of the Legia supporters after the 2-1 win.
Villa accused Legia officials of a “complete lack of cooperation” with themselves, the police, and the governing body UEFA.
After a thorough review of the incident, UEFA’s control, ethics, and disciplinary body took stern action against the Polish club for crowd disturbances, acts of damage, throwing of objects, and lighting of fireworks.
In addition to the financial sanction and ticket sales ban, Legia has been ordered to contact Villa within 30 days for the settlement of the damages caused by supporters.
These include broken high fences and a broken lighting pole.
The incident at Aston Villa is not the only one that has led to UEFA taking action.
French club Lens has been fined £25,800 and given a suspended ban from selling tickets to their next away European game following disturbances in the Champions League match at Arsenal on November 29.
During the match, Lens supporters damaged 50 seats.
