Well, this is a completely possible scenario, and it seems to me that it was discussed somewhere whether Mbappe will remain at PSG if Enrique suddenly manages to win the Champions League. But I agree that Mbappe will most likely want to leave for Real even in this case, because this is a long-standing desire, a point that needs to be fulfilled.
Sorry guys, in this case if saying mbappe go to madrid is an old wish then I do not agree with you, if we analyze in more detail mbappe's desire to leave PSG I think nothing more than PSG's failure so far to win the champions league trophy, when now Mbappe has won all the league trophies, top scoring awards, privileges at the club, And also a big salary, then what is Mbappe looking for at the moment in Madrid?
So far, all star football players make the Champions League trophy a pride when defending a club and the same as Mbappe today who also needs that pride.
If Mbappe had left Madrid because of his wishes, I think we might have seen Mbappe now in Madrid and not just rumours, because previously Madrid and Mbappe almost reached an agreement to work together in 2022, but in fact it was canceled just because mbappe had a fantastic offer at PSG at that time, I think if mbappe had a great desire to join Madrid then it seems that he did not refuse in last 2022 friend.
Kylian Mbappe is one player that's emerged as one of the very best players in the history of football over the last seven years and considering how big of a player he is at the moment, I believe he knows what's best for himself. Since he joined Paris Saint Germaine, the club have dominated the French league but have failed to win the UEFA Champions League competition and considering the importance of that very trophy to any player who wants to make a name for himself in football history, I don't expect Kylian Mbappe to continue to stay at Paris Saint Germaine when there's a club like Real Madrid who are very good in winning the trophy. Real Madrid president Fiorentino Perez having known the football abilities of Kylian Mbappe have never hidden his admiration for the French international and since the player is also in search of a club that'll help him win the UEFA Champions League competition, joining Real Madrid will be match made in heaven for Kylian Mbappe.
Wether Kylian Mbappe is leaving Real Madrid because of his selfish reasons of winning the UEFA Champions League title or not, the good thing about his potential move to Real Madrid is that he's moving to a better club than his current club and that's a very good decision and choice if you ask me
