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.
https://www.football365.com/news/psg-appeal-uefa-unfair-arsenal-champions-league-semi-final-turmoilIt is clearly unfair to PSG because the 5% is already set by UEFA and always required that 5% of the stadium's capacity go to away fans, so there is no reason to justify what arsenal did to PSG in this case. and regarding the security issue, I don't think that is something that needs to be used as an excuse for this, because if they really care about security then they can tighten the security more instead of reducing the 500 seats quota from PSG.
all these are just mind games that most of the teams are hoping to use to get at her opponents and see how best they can use it to there advantage. Other teams at this stage of the tournament have suffered similar fates and yet have managed to come out successfully and even used things to there advantage. What arsenal needs do at this point is to find strength in the midst of this and they can even get a win over PSG in their home ground. if you start to make excuses as to why you're not doing well based on whatever reason you have managed to carve for yourself, if it eventually affects you, you get to suffer even more when they succeed in their tactics.
Arsenal have become one tactical team that knows how to effective read her opponents and get the better of them. They can equally do same and get the better of PSG in both round. If they can win over real Madrid, it's also possible to win over PSG.
