Ahead of the Conference League final, Chelsea and Real Betis supporters have clashed with police in Wroclaw, with reports and social media footage indicating that tear gas was deployed. One video captures individuals lobbing items, including chairs, around a central city square. Additional footage reveals figures in police gear approaching fans – some donning Chelsea colours – before reportedly discharging tear gas. Earlier in the day, there had been peaceful scenes in Wroclaw square as fans of both sides gathered. However, things appeared to have changed by the evening, with police arriving. Chelsea and Betis are due to play in the Conference League final in the city on Wednesday. However, some of those watching the scenes unfold on social media voiced their concerns. Accounts varied over what caused the disturbance. However, there was plenty of criticism levelled at those seen taking part in the goings-on. "Imagine going to see your team in final, visiting a stunning European city, and decided to fight and vandalise restaurants and cafes?" one social media user wrote. Another simply urged people in the area to "stay safe". Another was left saddened by the behaviour of those in a city centre they visited not too long ago. "I was in both those bars just last year. Nice people, one of the best places I've been," they wrote. Chelsea reached the final by beating Swedish side Djurgardens in the semis, while Betis overcame two-time finalists Fiorentina to book their place in Wednesday's showpiece. Speaking in a pre-match press conference, Blues boss Enzo Maresca outlined how much the game means to his team. "The message over the last 48 hours has been, 'We did something important [qualifying for the Champions League], but if we want to confirm that we are becoming an important club again, we need to show the desire to win the game and the trophy'," Maresca said. 'So it's job done [in the Premier League], fantastic, and we're happy. But tomorrow is a different game, a final, and we want to win at any cost. "Every day we have something to prove, no doubt. What we have done [qualifying for the Champions League] is done. Now we have to prove ourselves again tomorrow. We have played many games this season in this competition, now we have just one more."
