That is not a parable because in the end at this time PSG has extended Mbappe's contract even though it is only a formality so there is no "if" in this case.
As for the future of Mbappe we will not be able to be that sure to determine his fate because in the end he determines himself. For the Arab club it will not be possible even when the transfer opened last summer, the 7-fold offer from the Arab club was flatly rejected and it will not be possible for Mbappe to leave with his current condition where he will still get more things at a big European club. And although several clubs are currently linked with Mbappe such as Liverpool and Chelsea but in the end everyone's interest clearly sees almost the same conclusion between Madrid and Mbappe because if we follow this discussion from when the domestic league is off and the transfer starts then Madrid is the strongest candidate.
I still think that his mind is at Real Madrid and to see that it is a prime position he could take is amazing. They have an amazing new young squad that is doing wonders even without him and they do not have a great superstar at the striker position neither. They have Joselu, which we all know is barely a mid table team striker so it is obvious that Real made the team ready for Mbappe if he wants to come there.
I believe that he is dreaming of the Real Madrid starting eleven every night with him at the striker instead and how many titles they could win. Just search youtube and see how many people tried that and you can see the results, people are going mad, winning 10 la liga in a row with such a squad because they are really that good. They are already good right now, would be insane with Mbappe at the front.
Joselu was originally borrowed only as an option for Madrid so that his position was not vacant for their attacking line so that with the arrival of Mbappe it could be a good thing but for now there is still nothing that really becomes a benchmark apart from various speculations about Mbappe's future because we can only believe that Mbappe will definitely leave PSG as for where his next destination we will not be able to know for sure about that.
It's just that great expectations are in Madrid but actually there are still a few clubs that can still be rivals as before with the interest of Chelsea or Liverpool but of course with the money they spent at the beginning of this season it will obviously be very difficult for these two EPL clubs so Madrid is still at the forefront if we talk about speculation.
