From the news reaching the rounds, PSG is sending an appeal to UEFA regarding their Tuesday Champions League Semi final first leg fixture against Arsenal. Before now UEFA always allows 5% of the tickets allocation to the away fans in it's competition, Arsenal has a stadium capacity of 60k of which 5% should be 3k but they only gave 2,500 tickets to PSG fans which is not up to the stipulated number. When they reached out to Arsenal, Arsenal said they can't give more than that citing it for security reasons because the London marathon will be held on Sunday. That's a silly excuse, are they trying to shut the away fans or what. Why do they want to bend the rules now? Out of 60,704 stadium capacity you are still finding it difficult to allow just 3,000 away fans in.
