Raul Jimenez has revealed there is no release clause in his Wolves contract.
The Mexican forward has emerged as a target for Manchester United and Real Madrid after an impressive campaign at Molineux.
Despite the revelation, Jimenez admits Wolves will demand a huge fee for his signature.
He said: "They (Wolves) bought me for €40million (£34.5m), they won't sell me for less.
"There is no release clause, but the clubs [in England], it is different how they are managed."
