On the one hand, Barcelona really needs money, an offer from PSG who is willing to redeem Yamal for a fantastic value can help Barcelona reduce the financial problems they are currently facing. On the other hand, Barcelona considers Yamal as their most valuable future asset, the player also wants to continue playing for Barcelona and has dreams of becoming a legend there.
PSG really wants to recruit Yamal from Barcelona because it is considered an ideal replacement to fill the position left by Mbappe. PSG is also taking advantage of Barcelona situation which really needs fresh funds to get out of financial problems. PSG must look at other players to build their squad if they fail to bring in Yamal, several top strikers are still available in the transfer market who could be used as new goal machines for them.
Currently, of course Barcelona is in quite a dilemma regarding the offer made by PSG, of course the offer that comes from PSG will not come twice in the future because the offer made by PSG is quite large and probably will not come from other teams for young players like as Lamine Yamal , like as you say, of course there must be careful consideration before Barcelona rejects or accepts the offer because on the one hand, the money will actually be able to help Barcelona finances improve in the future, apart from that, of course considering retaining Lamine yamal might also be a big risk for Barcelona, because when Lamine Yamal doesn't live up to their big expectations of course Barcelona will regret it, as happened to some of their young players who failed so far.
The chance of getting Lamine Yamal is of course still 50/50 to happens, so PSG should not only focus on Lamine Yamal and must try to find other good players, currently many young and talented talents are appearing in the Euro and Copa America championships so I I think it would be a good idea for PSG to monitor these players who are currently helping their national team for can their target to recruit.
