Barcelona coach Ernesto Valverde is looking forward to his return to San Mames.
Valverde faces former club Atheltic Bilbao for the first time since leaving over the summer.
Saturday's match will pair Les Leones against the Catalans and promises to be a special occasion for the Azulgrana manager.
"Each person has a reference team and for me that is Athletic. I was very happy there as a player and as a coach," he said.
"It's not easy, especially as a coach, because you always live with the pressure of your results, but I'm optimistic because I could enjoy [the game]."
