Wales boss Chris Coleman believes that it would be difficult for Swansea City to reject a large bid for their Spanish forward Michu.
The 26-year-old, who joined from Rayo Vallecano in the summer, has scored 15 goals for the club thus far this season.
However, Coleman told reporters: "If any player at Swansea is performing like Michu is then the big boys are going to look, and if they want you enough they will pay the money.
"As much as Swansea want to keep him, they won't be able to say no to that. They might say he is not for sale, but everyone is for sale at a price."
Michu is expected to make his Spain debut next month.
