Barca coach Pep Guardiola left Ibra on the sidelines, preferring to go with French veteran Thierry Henry in attack.
"Ibra is very bad. He is very sad and disappointed," Ibra's agent Mino Raiola told El Mundo Deportivo.
"Ibra wants to play more. He wants to be more important for the team, he's not perfect but he is a warrior, a fighter and I am sure he will come out of this quickly. He is a player with great character.
"Ibra helps the team a lot and provides assists but also scores a lot of goals for his team. I see other players who also score goals but don't provide assists and I think it's time now that Ibrahimovic started receiving assists to be able to score more goals."
