Williams himself wants to play in Barcelona and even agrees to receive a not too large salary (which will still be higher than in Bilbao) so that Barca can afford to have him on their roster.
I don't believe Williams will escape the temptation of money. If he leaves Bilbao to play for Barcelona, it could happen, because after all, Barcelona is still a better place for him to develop his career. But if other big teams offered and paid high salaries, I don't believe Williams would still choose Barcelona. For example, PSG, Man City vs Arsenal offered to recruit him. In your opinion, will Williams choose a financially strong team or still choose a team in a financial crisis like Barcelona?
It's quite difficult to answer your question, because it will come back to the players themselves. The fact is that in Barcelona there are still many players who are loyal and prefer to stay even though they have the opportunity to get a bigger and smoother salary, of course. However, they prefer to stay at Barcelona because of their loyalty to the team.
I don't know if that happened to Williams whether he would have the same thoughts or be more tempted by the temptation of money. The only one who can answer that is himself, and we'll see what happens next when he joins Barcelona and gets a tempting offer.
Ramos began his career in Seville, and I assume that he will finish it there. After his decision to move to PSG, it seems to me that with this decision he made his return to Real Madrid almost impossible. Yes, he is a very good player, but to end his career as a Real Madrid legend, he needed to remain in the team. With PSG he was unable to achieve anything significant, moreover, he was often plagued by injuries. Now he has returned to Seville and this is quite symbolic, he is playing where he started.
Real Madrid utilized the qualities of the Spaniard while PSG couldn't manage the behavior and inconsistent form of Sergio Ramos. With the constant unavailability for matches and this is really one big miss for them. Sergio Ramos is aggressive defender and have won the major titles with Real Madrid before leaving for Sevilla. He's an experience defender and a keyone for every manager and club he played for.
There is no doubt about the quality of this player, he is a very strong defender and has helped Real Madrid win prestigious titles such as La Liga and the Champions League. However, we know that if a player wants to retire at Real Madrid it is very difficult, especially when he is old and he still wants to play. I think Kroos is one of the very lucky players because he was able to retire while still wearing the Real Madrid uniform. Not without reason, this could also happen because Kross decided to retire when his performance was still very good and I'm sure many people were surprised by the decision he took. it is difficult or even impossible if Ramos wants to retire at Real Madrid now.
