The team who knocked Rangers out of last season´s UEFA Cup are thought to want more than £2.5million for the 25-year-old, although Cuellar´s agent, Pedro Bravo, confirmed the move is still a strong possibility, but far from a formality.
Bravo said: "Rangers and Osasuna are still negotiating the player´s transfer. They have not reached an agreement yet. We hope that it will be soon but it´s difficult to know."
