Sure, none of them ever wanted to leave. That's exactly how it went down
Anyway, you can't just leave PSG after 2-3 good years. That's just not happening. So a player like De Ligt should really think through if he wants to spent around half his top level career in France. I would understand not choosing Barca, but i wouldn't really understand choosing PSG.
Getting the chance to start is a legitimate concern and we all know very well that in Barcelona some players don't have to compete to get their spots. Being confident in your abilities doesn't mean it's wise to join a club no matter who is playing on your position.
Pique-De Ligt doesn't seem ideal and i wouldn't be surprised if Pique will stay a starter for 2 more seasons no matter how he or De Ligt would play simply because he's a legend and part of the group that pretty much runs the club these days, what would make things quite hard for De Ligt.
Of course money is, as always, a big factor and players usually never talk about it for obvious reasons so he has to say some bullshit like they all do but i wouldn't say it's the one and only reason someone in his situation would pick another club over Barca these days.
But the big problem with that mindset i see here would be that PSG just isn't a normal club. They don't let you go if you want to leave (especially to Barca) what was proven over and over with Silva, Marquinhos, Verratti. If you sign there for 5 years that means you will have to play in the French league for at least 4 years, probably even the full 5.
Raiola just sees the money of course, but De Ligt should know whats up with Raiola anyway so either he is stupid or just cool with it. We'll see what he wants.
PSG is as normal as any big club. It is just that the club was/is seen as some lower level club where Barça could just pick up players.
MU didn't let de Gea leave with the famous "fax" problem. They don't want to let Pogba go nowadays.
No City player is getting anywhere if they have not agreed. And so far, only the unwanted players have left.
Chelsea didn't let Courtois and Hazard leave before they ran down their contract.
Even Arsenal didn't let Ozil and Sanchez leave before they ran down their contract. Ozil finally renewed while Sanchez went to MU.
Bayern Munich took a stand last summer only not to let Lewandowski go when he was screaming he wanted to go to Real Madrid.
I remember the whole comedy when PSG tried to pay the release clause of Neymar between Barcelona, Tebas (didn't accept the payment) and the Spanish federation (didn't send the FIFA paper for Neymar to be able to play to PSG until the very last day possible, meaning he couldn't start the season with his new club).
Etc. Etc.
Bottom line is big clubs don't want to sell their top players. Didn't PSG sell Digne to Barça without any problem ? This transfer alone disprove the theory PSG wouldn't sell to Barça anything. It was after the attempt for Thiago Silva and Marquinhos. PSG will not just sell his top players if they think they can still keep them.
As for de Ligt, he will not join PSG. But in your theory, ofc he wouldn't leave PSG in 2-3 years. Do you know a club that will pay top dollar like that for just 2 years of football ?
I don't see why you laugh. You guys seem not to have good memory over here. I showed it to Luft the other day. I still remember the uproar here when Thiago Silva said he had a family to feed and rejected Barcelona offer.
Marquinhos keeps renewing and so was doing Verratti before. Why would you keep renewing so much if you don't intend to stay at the club ? You have to remind it is a two way street : the player gets improved salary every time he renews and the club is able to keep the player longer. Just this year, we hear story about Semedo wanting to leave because his role at Barça is not pleasing him but the club doesn't want to sell him. I don't hear Barça is a prison.
