This is the shocking moment that Chelsea and Real Betis fans fight in Poland before the final of the Conference League tomorrow.
Ugly scenes come from Wroclaw where Chelsea fans have arrived today, forcing Riot Police to spray tear gas and forcing the warring supporters apart.
Images placed on social media show a series of fierce collisions in paved streets outside the bars and restaurants of the city.
In one clip you can see a group of about five young men who laughed seats and swing glasses to another group of shelter in a building.
In the window is a large blue flag that reads: “Only London”, which suggests that it can be a place that is designated for Chelsea fans.
Riot Police storms over and pushes the aggressors with tear gas.
Another clip from elsewhere shows two sides that lobes rockets from the cover of two different pubs.
There is the constant sound of glasses of glasses and furious screams.
The police seem to be less prepared here – tackling the chaos without helmets – and can be seen as a cloud of objects that squat across the square.
In later images there are rows and rows of tuned agents who seem to have taken over control over the situation.
The blues will try to take the title tomorrow – and fans hope that the team will not be distracted by the drama.
Earlier, head coach Enzo Maresca received a shock when his forbidden winger Mykhailo Mudryk arrived unannounced in the city – and wore a Chelsea kit.
Mudryk has currently been suspended to play after positive testing on the forbidden substance Meldonium while having international service in November.
But it did not stop him that he made his own way to Wroclaw where he was noticed by fans who wore a club track in a steakhouse.
Maresca seemed overwhelmed when he was told that the £ 62 million Wideman was in the city.
He said: “To be honest, I'm just … Is he here or is he coming? He is here. I am happy that Misha is here.
“I don't know, I just said that. I'm glad Misha is here.”
