I think, Barcelona will soon loose their peace to sign in more potential players that will help them to maintain that first position in the la Liga league competition next season, so that their coach will experience another honor from the fans again. If Barcelona coach can release money to bring Kylian Mbappe in this summer, I think, Real Madrid or other strong teams will not challenge Barcelona next season because their defensive and midfield is very strong for their strikers to achieve many goals in this season. Since Karim Benzema has left Real Madrid to another team and kylian Mbappe manager is not willing to release him to Real Madrid, show that Real Madrid will still face the Same challenges they experienced last season.
Even if Barcelona wants to compete with real Madrid about offering psg a lot of money, I believe they will fail because real Madrid cannot be challenged with financial resources by Barcelona. And once more, if Barcelona wants mbappe, they will either sell some of their best players or give psg some of their remaining roster space. If you're talking about Barcelona, I believe they just said it in an effort to exact retribution for what Real Madrid did to them during the purchase of Arda Guller. Saudi Arabia recently made Mbappe an extremely lucrative offer that no other player in the world had ever received.
Apart from Saudi Arabia, there are no other teams that will pay a significant sum of money that is greater than real Madrid's own because we know that real Madrid is a team that can acquire players regardless of the cost, and in my opinion, apart from Al-Hilal, no other team will possess Mbappe than real Madrid because Mbappe is still interested in real Madrid and real Madrid is also in talks with PSG about obtaining Mbappe at any cost.
Barcelona is currently facing financial crisis, which has led them to explore alternative options. Because of their limited funds, they are offering multiple players in exchange for transfers. As of now, there is no negotiations between Barcelona and Mbappe. It's impossible task for Barcelona to get Mbappe under any circumstances. In this race, Real Madrid choose to remain silent. Despite their silence, yet no offer provoke Mbappe's situation, even a lucrative offer from Saudi Arabia. Without performing actively in transfer market Real Madrid is in a safe zone and favorites enough. Kylian would return to Madrid for free, and he will keep his word.
