Depends on the players.
Some has legacy here and would probably care for their post retirement career, and having good relationships with new president is huge part of it. There is a reason we have Marquez and Valdes back, along with Deco having relation to the club.
All of those left on good terms, even if on their own terms. I think part of it is a message to the veterans: We can help yoy to establish a career beyond being player, as long you keep things easily for us.
The likes of Busquets and Roberto and probably Alba has something to lose, Pique is wild card too.
OTOH, there are players who fight for legacy like Griezmann, he is a great player overall with great career, arguably the best player of his NT in one of their better generations .
Staying on high salary is cool, but adding trophies and being star of his team is rewarding too.
Abd then there are the bums, Umtiti and Coutinho etc, tgose whoowe us nothing and can just collect miney while giving us no leverage
