Agent expects Barcelona to keep hold of Montoya
Montoya comes off contract in June and has been linked with Arsenal.
Jose Maria Orobitg told Fichajes.com: "I think this winter, the club will not release Martin. They can always extend his contract ... Montoya is part of a list of non-transferable.
"Then, of course, if in January he has not played at all, maybe things can change, but I think not."
