I'm not so sure that Real left Mbappè.
He is their main target whatever this year or when his contract will expire and he will be a free agent.
I don't think Mbappè wanna stay longer in this PSG.
As far as I'm concerned and judging by the reports in the media, Kylian Mbappe remains at top of the list of Real Madrid targets that'll be signed next summer and reports has it in some media outlets that the Frenchman has already reached an agreement in advance to join the Spanish giants next summer.
Kylian Mbappe wants to win the UEFA Champions League title as well as the Balon D'or award and to he's convinced that his dreams are more likely to be achieved by at Real Madrid than with his current club Paris Saint Germaine so I think he'll definitely be joining Real Madrid next summer .
The right choice for Kylian Mbappe if He want to leave his club Paris Saint Germain is Real Madrid, because a team like Real Madrid will make him more developed and will win many titles including the Champions League because Real Madrid has a lot of great players who will pamper him with accurate passes. I think his opportunity to join Real Madrid will be lost if there is no agreement between the two parties in the next transfer market.
