The Turkish champion was thrashed 6-1 at home in its opening match, but claimed a surprise 2-2 tie with the Bianconeri in Turin in the Italian's first game in charge.
The club now faces two games against Copenhagen, while Antonio Conte's side has a double header against the Spanish giant, and the former Manchester City manager believes his side's fate will be decided in the final group game.
"With the point we took from Juventus the group has become more open and I believe that the group will be decided in the last group match against Juventus," he said at a press conference. "Until that match I believe that we won't make many mistakes and we will stay alive until the last match. Of course we respect our opponents and first we have to win tomorrow and then we have to carry on in the other fixtures."
