PSG will probably do a bid this week for Vlahovic.
This means Mbappè will probably be sold to Real Madrid too.
Juventus is expecting 70-80m for him
The Mbappe scenario is dicey; reports says Real Madrid will rather wait an extra year, get Mbappe on free transfer and give him a bumper sign on contract. On the other hand, with Juventus struggling with FFP; I believe selling Vlahovic to PSG for a huge fee will help them alleviate the burdens.
