So to begin with, at first both groups got along - they all sang these football chants together, like Poles supporting the Senegalese people and vice versa. When their anthem came on, the Poles clapped to show respect. But then, Senegalese provoked from the moment when we shot our only goal. They were irritated by the euphoria by the Poles, and they started throwing drinks and started to whistle at the Poles. But It was 2-1, so it was pretty obvious that they were going to win, so it was a very strange reaction from them. So while they were throwing drinks, a Pole threw a drink back at them, and then the benches started to fly around the whole place. In my video you can see the ending - they were the minority and were heading the exits because they got scared and then the police showed up. They also punched a few Polish women (there were no women with them). The Poles were also pretty concerned by the fact that there were families with little children, so it was really just an action-reaction system. Poles are pretty impulsive when it comes to fights.
The Senegalese also had like these fireworks with them - which was actually forbidden but the security didn’t seem to throw it away and fired it just a few moments right before the fight.
