The transfer market is always used to bring in new players, teams that performed poorly last season will make changes to add strength to their squad. Barcelona has been linked with several players in this transfer market, but so far has not brought in any new players, this is due to the club's financial condition which is still unhealthy and has clashed with FFP regulations.
Barcelona must improve their financial condition in order to be able to bring in new players, Hansi Flick has asked Laporta to prepare funds to be able to bring in new players, but they must release the players they currently have to get money so as not to clash with FFP rules. Barcelona must solve their problems one by one to improve their level, selling players is one of the options they can do so they can bring in new players.
Flick said publicly at a press conference that Barcelona does not need new transfers, and Laporta asked Xavi for new transfers, or rather demanded them, which is why they had a conflict. I understand that Barcelona has problems, so they need to refrain from new transfers, but why did they let Felix go? If I'm not mistaken, they said that they should keep such an important attacking player by any means, especially considering that they do not count on new transfers, or did they target Williams and therefore let Felix go? But PSG will not let them do this, they have much better financial opportunities and they can lure Williams...
