Well, don't accept and stay or go to another club.
You guys do this enough though and people will simply decide to not go there in the first place; avoid the problem entirely.
What you keep missing with this talk of contracts is that they HAD to be written. When Barca had to defer payment of their wages it had to be listed as a restructured contract, because I’m positive it would violate league rules to simply “promise” to pay later. But that was supposed to be formality. In good faith those players were to get the money they had earned for the games already played. Reading the articles written at the time we know this not just because they said it, but because they agreed to write in up to 3% interest on the portion of their future salary that was remuneration for games already played. They were in essence “loaning” you that money. That was from quotes from your teams reps in ESPN in an article from November 2020.
You owed them money, and the answer being given is that they can accept you not giving it to them, or they can leave … and also not get the money.
Now, anyone who plays for you, coaches for you, or represents you in any way is a champion of abusing players, plain and simple.
Nothing your club says to a player can ever be trusted again.
And using the club media outlets for what is essentially emotional blackmail and harassment takes it to a level that is well beyond “not ok”
Barca could have done the right thing by their players, and they would have been fine. They just might not have been able to sign Lewandowski. Not being able to sign a striker is not a good reason to destroy the credibility of an entire club, defraud players, and possibly cause them genuine harm.
