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.
It seems that Barcelona is currently confused about which players they can sell in order to be able to bring in better new players without having to clash with FFP regulations. Because Hansi Flick's suggestion about providing funds to be able to buy new players for Barcelona is not wrong because that is what the Barcelona team itself needs, but when Barcelona has to choose to sell one of its players to the transfer market at this time, of course it will make the team feel dizzy to see who is more suitable to be released in order to have the opportunity to buy other players before the season starts.
