PSG only has two options for Mbappe, first to offer a new contract, and secondly to sell Mbappe if they refuse the offer of a contract extension. PSG already realized that Mbappe likely did not want to be in Paris any longer after Messi's departure, he would not be able to lead PSG to win the Champions League title as they had dreamed of.
I just don't want Real Madrid to fail to get it from PSG even if it costs a lot, but it's worth the quality. Mbappe is interested in playing for Real Madrid, but I believe he is also interested in the Premier League which might make him a Ballon D'Or winner. The Premier League is more competitive than La Liga, but La Liga isn't bad for Mbappe.
I think it's time for Mbappe to leave PSG to join Real Madrid, Mbappe can get everything at Real Madrid instead of having to stay at PSG. Real Madrid is a strong club that has achieved success in the UCL and La Liga, Mbappe will find it easier to win the UCL trophy if he joins Real Madrid.
Mbappe's quality needs to be developed in a more competitive competition, he can compete with Haaland in winning the Ballon d'or. Real Madrid's strength will increase if Mbappe fills the front lines of Real Madrid, especially since Real Madrid has just officially announced Bellingham transfer from Dortmund.
