Barcelona are in a very tumultuous position following the news of Lionel Messi leaving, and the CVC deal signed by La Liga.
The board released their statement confirming their stance on the issue shortly after the departure of the player was confirmed. In the short run, an injection of €2.7 billion into the league, of which Barcelona would receive €270 million due to the amount of revenue they earned seemed like a very good deal.
However, it was later revealed that the league had signed a 50-year-deal that the club referenced in their statement. Additionally, this would result in Barcelona losing over €800 million in the long run, which amounts to 10% of La Liga. Lastly, all the clubs in Spain would have to agree to an anti-super league clause. Only three clubs remain in public support of the Super League, and Barcelona are one of them alongside Real Madrid and Juventus.
Keeping that in mind, Barcelona did not receive anything from the proposed deal since they believe that they have been treated unfairly by the league in relation to the CVC contract. They were not consulted, and were not presented the details before their media rights were tampered with.
Real Madrid have already decided to sue the league as a result of their decisions, and in the wake of the loss of their greatest source of revenue, Barcelona could join their Clasico rivals in a legal battle against La Liga itself.
