Swansea City have slapped a £30 million price-tag on Michu.
The 26-year-old has been one of the stars of the Premier League season since moving to the Liberty Stadium from Rayo Vallecano for a bargain £2million in the summer.
Swans boss Michael Laudrup said: "Joe (Allen) went to Liverpool and you know more or less what they paid for him, but a guy who has scored many goals must be worth a lot more, so you work out the figures.
"I don't think anyone will come with that money so he will stay here."
