Few things why that won't happen IMO :
- You don't buy a 130+M€ player for loan it.
Oh, and someone once trashtalked me about him not breaking the record for transfert. Hey dude! :)
You can here it here (and I say that since long months, now you'll maybe put some credits on my voice) that he will not go under the record, and the club will not sell him except if he ask.
"- If I'm Chelsea, Manchester, and I offer you 100M€ for Mbappé?
- There is absolutely no price for Mbappé. Except if he ask us to leave, then, we will sit around a table and discuss. But for us, he's priceless.
- So you can say no to a 100M€ bid?
- Yeah of course. Sure. "
Everyone has a price.
