Layvin Kurzawa is joining Paris Saint-Germain after deciding the time was right to leave Monaco, the principality club's vice-president Vadim Vasilyev has said.
Vasilyev, who also backed new signing Fabio Coentrao to "contribute a lot," spoke as 22-year-old Kurzawa was set to complete his move to the Ligue 1 champions this week.
The France international, who came through the Monaco youth academy, could face his former club when they meet PSG on Sunday.
Monaco will be paid around €24 million for the left-back, and Vasilyev told RMC: "We reached an agreement with Paris.
"We wanted to keep the player. We talked to him a few times, but he had decided -- he really wanted to go to Paris.
"It's his choice. We wanted to keep him -- but if a player wants to leave and a club makes us a very good offer, we do it. I can confirm that it's for a very significant amount."
Monaco have completed the signing of Coentrao, 27, from Real Madrid as Kurzawa's replacement.
The Portugal international moves to the Stade Louis II on a season-long loan, and Vasilyev believes coach Leonardo Jardim will benefit from the new arrival.
"I have brought in an international with a lot of experience," he said. "We've been heavily criticised for only bringing in young players. Now we've got an experienced player who will contribute a lot."
