He will leave.
That's a bit deceiving and ignores his actual answer. He said that Monaco had no intention to sell him, have a project around Mbappé and Mbappé wants to stay, they will offer him something latter in the season too. He also said that with the QF qualification Monaco finances are in the green, therefore they don't have to sell but will sell some players because it's part of the project but they are in a position to choose. At the end of the interview the host insisted and ask for a guarantee that Mbappé wouldn't be sold and Vasyliev said that he won't because nothing is guarantee in life.
