Eusebio Sacristan says he would snub Barcelona approach
Luis Enrique announced last month that he will step down as Barcelona manager at the end of the season, citing the need to rest.
Sacristan, who made 250 appearances for Barca as a player and managed the club's B team, is said to be one of the leading contenders for the Nou Camp job.
But the 52-year-old insists he is fully committed to his time at La Liga rivals Real Sociedad, where he only signed a new contract last month.

"I'm flattered that I'm considered as a future option for Barcelona," he told AS. "But it doesn't take a second of my focus on my day to day.
"Would I turn down an approach from Barcelona? Yes, I can assure you. I'm 100 per cent convinced about that. I don't see that possibility.
"All that is happening now is thanks to La Real, which after my four years with Barcelona's youth sector took an interest in me and took a chance on me.
"Barca didn't consider me when I was part of the club.

"That is what I would have liked. I have to be committed to La Real after they believed in me and gave me a great opportunity.
"All that I wanted, I have it here and I wish for it to continue for as long as possible – I have found the perfect balance between my personal and professional life and that is not easy.
"For me it's not essential to be in a club that allows me to win titles more easily because I've already won those as a player and as an assistant.
"For me what is more enriching is to do great things with La Real."
