Pedro scored the only goal of the game in Barcelona’s 0-1 away win.
Iniesta told Marca: “We played a complete game, we combined well and created a lot of chances, but maybe lacked a goal to kill the game off.
“Ibrahimovic contributes a lot to the team, even when he doesn’t score, but a player of his quality will score quickly.”
Rafal Marquez added: “It was a complicated game, because the pitch was not in great shape.
“We had a lot of chances in the first half, but did not take them all, and in the second half we had to deal with their attacks.”
