It's clear if barcelona needs to sell a lot of players. Gundogan cannot be registered by barcelona caused by la liga has been blocking barcelona to register new player until the club raised 200 million. Barcelona is still in the bad position right now.
Ansu fati, ferran torresm, etc have been refusing to leave from the club which is very bad for barcelona. The summer signing may not be registered while we are very close to the opening match of la liga.
In last five years Barcelona finances are going from bad to worse as they are completely going down and have no fair chance until 2047 to clear their debit which is currently standing at the £1.35 Billion with this few players which Barcelona needed to be offloaded are also not want to leave club which making things more troubling even right now they are not able to register their players for the new season which is surely not ideal situation for them.
Recently we have few rumors with they were looking for the few players to be sold, but all refuses, and their few big signings are also having big loses as these all were never been having not positive results as they were expected, and now they have to sell them on very low price which create more financial trouble on them hopefully things take good change for them, and they are able to fix this all without any big trouble in near future.
