Real Sociedad sports chief Roberto Olabe says coach Imanol Alguacil's continuity is crucial to their success.
La Real are on track for Champions League qualification.
And Olabe said: "The importance of Imanol is absolute.
"He is a boy from Orio who has lived what Sanse means, the first team and what it means to be dismissed because someone thinks that you are not for Real Sociedad and you have to go find yourself a life.
"And after that, he has returned to train academy teams and the youth team. And he had the humility to join the first team on the condition that he return, and that gave him security and allowed him to look at the Roman circus from another perspective. Everything was a process."
