Club president Jokin Aperribay publicly addressed the situation, revealing that despite interest from several top European sides, no player, including Zubimendi, has yet communicated a desire to leave.
"Zubimendi is the only player we've spoken to. Clubs have asked us, but no player has told us they want to leave," he told reporters.
"We've told Martin to go to the national team calmly, to think about it, and we'd like him to stay. We know there are several options. Something may come to fruition or not... I don't see it happening in the short term. We don't see it that way, so we have to wait and see."
