Not necessarily true. If we truly are the only club after him, they need the money and I can see them budging. EPL punks can bid all they like, but he has said (and his agent) that he doesn't want to go to England. Athletic Madrid can try and be firm, but if he wants to leave this summer and we are the only club after him, then they will have to be flexible.
Its not like Juve, Real, Chelsea, Shitty, Manure, Barca, Bayern and Lecce are after him to start a bidding war...he has narrowed it down himself along with his president. It seems pretty cut and dry.
