Real Madrid will be a top priority for Mbappe, that is if Real Madrid still intends to get him, because I don't know whether Real Madrid has made a special approach to Mbappe or not, and what is spreading now is just a rumor that says Real Madrid still really wants Mbappe to be part of their squad.
If the situation remains the same, it will be a great missed opportunity if Mbappe returns to doing things like last season where he chose another team than the team that has actually been his dream since childhood.
As far as I know, Florentino Pérez is still interested and has a plan to sign Mbappe. But he stated Real Madrid possibly sign Mbappe next year. We all know that Mbappe's price is very expensive, Real Madrid is waiting for Mbappe's price a bit lower. Mbappe also has confirmed that he wants to stay in PSG this season. However, if it is possible, Real Madrid may sign him this year because Real Madrid is urgent to have a new striker. We don't know what to happen in the next few weeks, Mbappe may change his mind and decide to leave PSG sooner. Let's see where Mbappe plays this year!

Mbappe has a special contract with PSG, that's why he is unable to leave PSG very soon. It is not about the money only, it is about how Real Madrid ability to negotiate with PSG. I'm sure Real Madrid already reached a personal agreement with Mabappe, but Real Madrid has difficulty to reach an agreement with PSG management.
