'Due to the extreme violence, there was no other option than to prevent away fans from entering the stadium. Everyone's safety is our priority, and we clearly had no other choice.
'There can never be a place for such appalling behaviour, and this is something we and the wider community should never have to experience.'
Mail Sport understands 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 percent of the stadium's capacity, which equates to 2,100 tickets for Villa Park.
In an official statement from Legia, they accused Villa of refusing to allocate tickets to away fans in accordance with UEFA rules for a UEFA Europa Conference League match.
'Rather than diffuse potential tensions before the match, restrictive measures by Aston Villa FC as the host club unnecessarily worsen the atmosphere. In our opinion, such measures are counterproductive and unwarranted,” they wrote.
'In a recent development, Aston Villa FC has resolutely refused to adhere to UEFA competition rules by refusing to allocate the stipulated quantity of tickets to visiting supporters.
'Legia Warsaw had put forward a compromise solution, proposing an allocation of 1,700 tickets for their loyal supporters – a figure equivalent to the number allocated to English club fans traveling to Warsaw. This proposal was officially accepted and duly documented in the UEFA delegate's report, dated 21 September.

“In light of this agreement, Legia Warsaw supporters began their preparations for the journey across the English Channel, incurring various costs, including airline tickets and hotel reservations.
'However, on November 2, Legia Warsaw received an unexpected and revised decision on ticket allocation, blatantly ignoring the previous agreements. The number of tickets was reduced to just 890, a staggering reduction of more than 50%.
'Faced with this untenable situation, Legia Warsaw has repeatedly appealed to Aston Villa FC and urged them to respect the rules adopted on September 21.'
Villa returned later in the evening with their own statement condemning the violent scenes on the streets outside their stadium.
Villa said: 'Football club Aston Villa can confirm, on the advice of West Midlands Police, that no away fans will be allowed into Villa Park for tonight's UEFA Europa Conference League match with Legia Warsaw, following large-scale disturbances outside the stadium caused by visiting supporters .
'The British security authorities, UEFA and Aston Villa, announced on 2 November that the allocation of tickets for away fans for this match would be reduced to 1,002 on the advice of the security authorities as a result of previous large-scale disturbances caused by Legia fans last year. month at AZ Alkmaar.
'A number of Dutch police officers were injured during those disturbances. As a result, UEFA banned Legia supporters from traveling to Mostar for their match against HSK Zrinjski.

'Despite numerous requests for cooperation from Legia Warsaw regarding their traveling supporters, especially in the last two days, no assistance was received from the visiting club regarding the serious safety issue of the away fans attending Villa Park.
'The club has repeatedly, including this morning, in collaboration with UEFA and all relevant authorities at Legia, expressed their concerns that supporters without tickets were attempting to visit Villa Park.'
