I would like to give the example of Atalanta who for years has been up and down from Serie B to Serie A
in the meantime they built starting from the youth teams, having no money
now they arrive peacefully in UCL (not this year) where there is the money.
the only way to rise again is this, to invest in young people
Barcelona had to wait for a longer time and not spend too much money right now because their financial situation is too bad. And the way they are going about it is not going to help at all. A long-term plan is certainly the way to go for Barcelona but it feels like they are looking for a lot more short-term solutions. And I also think that Barcelona should invest in youth players right now. That will help them to really build up players for the future and they will also be loyal to the club.
if they are focusing on a long term solution something like keeping everything as it is currently not signing any more players and sticking with the players they currently have to manage their finances well, they won't be able to win the league, they won't be able to to get far in the champions league and with that they will be a club with less attraction worldwide and less attraction means that TV channels and newspapers and sponsors are not wasting their time going after barcelona, but if they invest money in good players and manage to win la league and go far in champions league then they will be able to earn more money too
