Considering stadium security issues

I'm thinking this might relate to either the Copa del Rey or La Liga, particularly the rivalry between Barcelona and Athletic Bilbao. I need to highlight that Barcelona is temporarily playing at the Montjuïc Olympic Stadium during renovations. There are concerns about away fans and effective segregation, which could impact attendance and sanction risks. La Liga likely mandates a number of away tickets, but I need to be cautious about the specifics. I can summarize neutrally and ask the user what additional information they want.Drafting a news summary

I’m thinking about creating a concise news summary regarding Barcelona’s decision not to allocate away tickets to Athletic Bilbao due to security concerns at the Montjuïc Olympic Stadium. It's because of the inadequate segregation and safety measures for away fans. This impacts travel arrangements for away supporters and could lead to issues around ticket sales and transfers. I can ask the user if they want an English translation, a timeline of events, fan advice, or social media briefings.
