Porto coach Vitor Pereira cannot guarantee Tottenham and Manchester United target Joao Moutinho staying.
Porto have always insisted they are not looking to sell - but coach Pereira admits that if somebody wants to pay Moutinho's buy-out clause of just over £30million, there is nothing they can do.
"We very much want him to stay and we are not looking to sell," he told Abola.
"But this is football and you have termination clauses, for us he has been great and helped us achieve the results we have."
