Sparta Prague 'hooligans' have taken to social media boasting of attacking Rangers fans.
The Czech side's adult fans had been banned from attending the game but 10,000 supervised under-14s were allowed into Letna Stadium.
However, the tense match saw Rangers midfielder Glen Kamara jeered after his first touch of the ball - with the abuse continued throughout the game.
Afterwards, Sparta Prague 'hooligans' took to social media boasting of a violent clash between supporters as fans poured onto the streets.
In a post on Instagram, the thugs claimed to have cornered Rangers fans in a pub on the hunt for a fist fight outside.
Locals reportedly began retaliating before bar staff called the police but the hooligans claim to have beaten up at least two Rangers fans.
An account called hooligans_cz wrote on Instagram: "After match we made group of 20 people and tried to find Rangers.
"Luckily we found them in one pub in the centre. Two guys told us that they are in 40 people.
"So we came in front the pub and asked them for fight on hands.
"Surprisingly the guests started to throw glass, stones and chair.
"We went through and wanted to fight on hands, but the p*****s still just threw some s**t. Really just about 2-3 Rangers went out of pub but got beaten.
"After minute the Staff called police so we had to back off the streets. Shame for western BLM suckers."
During tonight's game young Czech fans were slammed online for the 'racist abuse' of Kamara.
The Finnish star's lawyer Aamer Anwar described the repeated booing of the player as 'shameful' on social media.
He had also previously warned that Rangers face a “genuine risk to life” ahead of the match.
A young Sparta Prague fan was even pictured with a 'Kudela team' poster during the match.
Ondrej Kudela, who in fact plays Prague Sparta's rivals Slavia Prague, called Rangers midfielder Glen Kamara a “f****** monkey” during a game last season.
The racial slur during the game at Ibrox saw Kudela hit with a lengthy ban - and Kamara also punished for an alleged altercation in the tunnel.
The Europa League match ended with Rangers losing 1-0 to Sparta Prague at the Europa League match.
