The two sides played out a goalless draw in the first leg last week, but Turan has said that there are 'no favourites' for the clash tomorrow evening.
"[0-0] is neither an advantage nor disadvantage, just a fresh start," the Turkey international told the Andadolu News Agency.
"We will see. We are a team that fight for every ball; for every second of the game.
"We believe in our ability, our dream. We chase our dreams and go as far as possible to realise them. Atletico supporters know that we give everything we have on the playing field before leaving it - win or lose. We believe we will reach the final."
Turan is expected to return to the Atletico XI against Chelsea following a period out through injury.
