Wolves boss Julen Lopetegui admits he's been blocked from extending the stay of off contract players.
Joao Moutinho, Diego Costa and Adama Traore are all coming off contract.
Lopetegui, after their final day thrashing at Arsenal, said: This is a problem. You have players you want to re-sign and you can't because they are like a new signing in financial terms.
I am not a financial advisor, I am a coach, I can say if I want or don't want these players but after it is about the possibility of the club.
That is why it does not depend on me. I know that the sporting director and his staff have worked very hard in these five months and they have different targets for the squad.
But to execute any targets you need to know how much money you have. If not it is impossible."
