Martinez calls on Athletic Bilbao to make transfer decision
Athletic have turned down a bid from Bayern Munich as they hold out for 46million and the delay is frustrating Martinez.
"Like I have said before, I just have to wait and I hope that there can be a quick resolution," the 23 year-old told Bild am Sonntag.
"I cannot say much more about the situation. I am relaxed and I am training to maintain my fitness and I just hope that a decision can be made soon."
