Kang-in Lee is stalling new contract talks with Valencia.
Superdeporte says the South Korean does not want to accept the contract offer put forward by the club and his departure could be an unexpected surprise in the last few hours before the market shuts.
His contract expires in 2022. It's not a question of economics, but instead, he wants a better sporting project.
French, German and Italian teams have shown interest.
The club don't want what happened with Ferran Torres - City getting him cheap a year before his deal was up - to happen again, so might sell now.
