Barcelona coach Luis Enrique was relieved to overcome Champions League opponents Borussia Monchengladbach.
"We've seen how difficult it is to win in all the different stadiums and in the group, which indicates that it is very close and that there are no weak teams," the Barcelona coach said after the match.
"Our goal is to win the next match, and then the next one.
"We'll be doing our homework."
The man who changed the match was Turan, who came off the bench on the hour mark, before equalising just five minutes later.
"We need all players to perform, no matter what point they come into the game," Luis Enrique said.
"I have been pleased with Arda [Turan] since last season.
"It's not easy to adapt in the kind of situation [of not being able to play for half a season] in which he arrived."
