Barça is going through a difficult time after the news that has emerged in the last few hours. Everything started with the unexpected departure of Iñigo Martínez, who left for Al-Nassr for free after terminating his contract. Initially, that move was supposed to free up money to register the new signings without difficulties.
The departure of Iñigo Martínez hasn't solved the registration problems at Barça
However, although Iñigo's farewell is official, several footballers still aren't registered in La Liga. This has caused concern, because some could be left without playing and end up in the stands. The most striking case is that of Joan García, the new Barça goalkeeper.

Joan García still isn't registered in the competition and it seems unlikely that he will be for the first matchday of the national championship. Barça will debut next weekend against Mallorca and, for now, only Iñaki Peña could take the goal. This situation worries the fans and the sporting management.
Joan García isn't registered for La Liga and his participation in the debut is uncertain
There are only two possible ways to solve this situation. The first option is painful for Barça, since it would involve the departure of more important players to free up salary space. Without those departures, the goalkeeper's registration can't be completed in time.

The second possibility is linked to the money the club can obtain from the sale of Camp Nou's top-level boxes. If the full payment from that operation is received, Barça would have room to register Joan García without needing more departures. For now, that amount hasn't been fully received.

If the club can't unlock either of these two options, Joan García won't be able to make his debut this season, which complicates the defensive outlook. The board is working against the clock to solve it, but uncertainty remains. The fans are hoping for a quick solution to avoid bigger problems.
Ultimately, Joan García's situation at Barça reflects the financial and administrative difficulties the club is facing. His immediate future is in the hands of decisions that haven't yet been finalized. Only time will tell how this story ends.
