According to several sources from Spain Mbappé just asked to PSG to be sold to REAL MADRID for this January.
If you had followed up the news properly, you would have heard and also read that PSG may be willing to release him since he is unhappy with the coaches attacking style, wants to play in the premier league and reportedly not in good terms with Neymar, but the only club that they are willing to release him to is Liverpool and not Real Madrid. Liverpool will really need his services to compliment their attack because they have not been the same since Mane left and Darwin Nunez isn't seeming enough.
Read Full Story HereLiverpool will not match with mbappe because at this time klopp is focusing on waking up nunez. the best place for mbappe if he really wants to leave PSG in January is MU, Ronaldo and mbappe have a pretty good relationship, so he will be very happy to be there, besides that manchester united is also a rich team and for mbappe's salary issue it's not a hard thing to them.

Trying to be like Cristiano Ronaldo and emulate the milestone he has achieved in his career so far will be very difficult to achieve for anyone that call's idolize Ronaldo, cause you have to do better twice if not thrice of all he Ronaldo did in his journey so far.
Having said that, Manchester United has some attacking players and don't have plans considering a big money move to Manchester United during January transfer window, they need top quality players but not the humble Kylian Mbappe.
I'd love to see that Kylian Mbappe and Erling Haaland goals hunt in the premier league , I've always envisaged that coming, but as it looks Real Madrid will never come back hunting for Kylian Mbappe, rather best end point for him will be Liverpool since Luis Diaz is currently injured. Manchester United are being linked with the switch of Gakpo from PSV, that deal much more likely since both Erik Ten Hag and the young lad has and shares a single agent. Truthfully, I can't wait to see Kylian Mbappe taking the next private jet to finalize a deal with the top premier league club's.
