Now Mbappe will definitely not be able to leave PSG because he has a contract until the end of the season, but he can already start negotiating with other clubs. I read the latest news today that Liverpool wants to get Mbappe, I don’t know if this is true (as the French publication Le Parisien claims), but it seems that Real is still the number one contender. I don't think PSG will try to stop him, they will get big money for Mbappe and it looks like they are already looking for his replacement.
Mbappè can't leave in January if PSG doesn't want to sell him, but if Madrid is able to buy Mbappè at the agreed price I think PSG will let him go rather than PSG having to lose Mbappè without getting any profit because Mbappè is PSG biggest investment at the moment so let it be this player being free is a painful thing, if in the end Mbappè leaves PSG, I don't know what will happen to the team because so far Mbappè has been a key player for PSG in achieving success, whereas currently PSG doesn't seem to have any rumors relating to the striker Mbappè replacement.
Usually as we approach for the transfer window we have many rumours and other related things in news which create good heat, and we also have good masala from the media so now same happening while we are jumping for the transfer window many reports are coming about Mbappé even nothing is official but still if we have Mbappé out of the PSG then surely management will bring suitable replacement quickly because they also understand impact of this transfer on team.
But, in case he leaves then surely something happen, but they are capable of having recover from this and bring positive changes as well with most chances we will have Victor Osimhen and Vlahović as his replacement at the PSG few weeks back we have talked about this which clearly indicate Mbappé and Luis Enrique are set for working together but now we to wait about this all how this all will be ended.
