Bayer Leverkusen have slapped a €100m price-tag on winger Moussa Diaby.
The French attacker is being chased by some of Europe's biggest clubs ahead of the summer market.
PSG and Real Madrid are both keen, while Manchester United expressed interest last season. Diaby has a deal to 2025.
A source told L'Equipe: "His directors are not willing to let him go for less than 100 million euros.
"Moussa Diaby is worth a lot!"
