Three police officers were injured outside Villa Park after missiles were thrown at them by Legia Warsaw fans.
The Europa Conference League tie between Aston Villa and Legia began without any away fans inside the stadium, with the travelling supporters contained in a car park behind the Witton Lane stand after clashing with police.
Mail Sport understands that Legia were unhappy with their reduced allocation after Villa reduced their ticket allocation to just 890 based on advice from the police and Safety Advisory Group.
UEFA rules allow the visiting team five per cent of the stadium’s capacity, which would equal 2,100 tickets at Villa Park.
Birmingham Police tweeted: ‘We’re currently unable to allow away fans into Villa Park following disorder outside the stadium which has seen missiles thrown at officers.

In an official statement from Legia, they accused Villa of refusing to allocate tickets to away fans in accordance with UEFA regulations for a UEFA Europa Conference League match.
‘Instead of relieving potential pre-match tensions, Aston Villa FC’s restrictive measures as the host club unnecessarily exacerbate the atmosphere. In our opinion, such measures are counterproductive and baseless.’
Legia supporters made their way towards Villa Park ahead of kick-off, but were met with a barrier and a wall of police officers wearing helmets with visors to protect themselves.
