I would rather than call him to stay in PSG and does nothing rather than playing for PSG. The management is not interesting to put him in the main squad at this moment. I can only say mbappe must accept the truth if the team is not willing to use his service.
Mbappe is gonna be benched for the whole time. Enrique already got advice from PSG to do that, since the problem still remains unresolved at this moment. I would like to see mbappe's expression to see his teammates were playing in the league 1.
PSG considers more sanction for him caused by he makes everything become complicated not only for the club but for him and his mother too. Chelsea is not interesting to fulfill mbappe's requirement.
That's the reason why chelsea has been refusing to buy him from PSG at this moment. Chelsea prefers to recruit another player of instead of him from PSG.
PSG just has to let this season go, whatever happens this season happens, maybe no UCL win at all, maybe not even get the title, hell not even the cup. I do not care what they end up losing this season, let it be and then get rid of Mbappe, do not even offer him a new contract at this point, let him leave for free if you have to, and yes it's a lot of money and they would rather sell him but there is no way they are selling him as we can see, he doesn't leave at all.
Then we need to consider the fact that we should be getting a whole new PSG, possibly without Neymar as well, get the young better players that wants to play there next season and then you could see them do a lot better on the long run without a doubt.
