The unrest occurred ahead of kickoff in the Europa Conference League game at Villa Park, and the police denied entry to travelling fans, leaving the away stand empty.

“We’re currently unable to allow away fans into Villa Park following disorder outside the stadium which has seen missiles thrown at officers,” Birmingham Police said in a statement.

“Three officers have already been injured and a significant policing operation continues.”

Legia Warsaw said Aston Villa had given the Polish club a lower allocation of tickets than they were entitled to under Uefa regulations.

“Instead of defusing potential pre-match tensions, Aston Villa FC’s restrictive measures as the host club unnecessarily exacerbate the atmosphere. In our view, such measures are counterproductive and unwarranted,” Legia Warsaw said in a translated statement.

Aston Villa did not immediately respond to a request for comment.

“No away fans were allowed into Villa Park for this evening’s Uefa Europa Conference League fixture with Legia Warsaw on the advice of West Midlands Police following large-scale disorder outside the stadium caused by visiting supporters,” the Premier League club said in a statement on social media platform X, formerly known as Twitter.
