Everyone will agree that Mbappe is always rumored to be with Madrid but however as long as everything is still not clear then in the end things like this become a wild speculation that will definitely continue to blow and more and more because of the traffic and headlines that are always sought after including for some of the news circulating now no matter true or false but every day there is a lot of the same news where Mbappe and Madrid are always a hot topic.
But we also can't do anything at this point because for the news now everything is also still based on rumors even though there is a strong possibility that it will happen but as long as there is no truly valid source or maybe there is still no confirmation from Madrid, PSG and Mbappe then everything will be hanging including the news you linked to today where even though there is indeed a clarity about the time when Mbappe will be introduced after the European Championship but there is a word "rumored/reportedly" which means everything is still uncertain because in the end there is still no further confirmation and everything is still hanging.
We still have to wait even if we want news that Madrid is the next club for Mbappe but until there is further confirmation this will remain a rumor with a lot of speculation in it.
Speculation regarding Mbappe move will become clear when the season ends and the transfer window opens again, for now I agree with what you said. As long as there is no official confirmation from PSG-Madrid-Mbappe, it is still considered a rumor. Personally, I am very curious about how this transfer saga will be resolved in the future, after the long, drawn-out wait.
Luis Enrique will look for a player if Mbappe leaves, several names are also rumored to be targets for PSG in the future, such as Osimhen. For now, Enrique has to think about how PSG can progress further in the Champions League, while Mbappe is still with them at the club. For Ligue 1 itself, I feel PSG will remain stable and will continue to be the rulers even if Mbappe leaves later.
The top club with the most potential to recruit Mabppe is Madrid, Perez will return to continue build the Galacticos in the latest volume. On the other hand, maybe in the future PSG will change their wasteful transfer style, they will not build an expensive squad surrounded by star players, because that does not guarantee that they can get the UCL trophy easily.
Because indeed things like that cannot be denied even though there is a lot of speculation circulating at this time, in the end this is just a rumor as long as PSG, Madrid and also the party from Mbappe do not provide clarification about the current rumors so that this will not be completed and indeed we just have to continue to wait until the end of this season is finished.
As for the replacement problem PSG will definitely be prepared with it because they know their internals and until now it is not wrong if it still continues to make Osimhen a priority because after all he is currently one of the players who is suitable as an option but his future cannot be determined now because once again this will be a situation where clarity will be revealed separately at the end of the season.
As for Madrid's Galacticos, they have tried to discard that image but indeed if Mbappe comes to Madrid then indeed they are indirectly creating new galacticos with a very dangerous version of young players.
The average age of Madrid players is currently below 30 years but the performance they show is very terrible.
