It's not that simple. Barca always calculates the financial year with at least CL quaterfinals and 1st-2nd place in LaLiga. Just to reach top4 isn't enough to be profitable on the current wage system Bartomeu introduced.
I'm not an expert in Barcelona, obviously. but... to what extent does the "Bartomeu wage system" still exist?
Barcelona had extremely highly paid players like Messi, Griezmann, Suarez, and Coutinho. They are all gone. Dembele and Sergi Roberto renewed on lower salaries, Umtiti spread his wages across many years. Who does that leave, De Jong, Busquets, Pique, Alba, Ter Stegen? Most of them have been around for a long time and it's normal that they have high salaries. I think they have comparable salaries to Courtois, Kroos, Modric, Marcelo, etc.
hope our young players will play the whole year without any injury and low form
You have to admit that if you're concerned about
loss of form and injury, buying a bunch of over 30 players is a weird strategy.
