The Cote d'Ivoire front man led Chelsea to a surprise victory in last season's tournament, scoring the winning penalty in a dramatic final victory over Bayern Munich, and wants to experience the sensation of winning Europe's top prize once more.
"It's a big pleasure to play in the Champions League," he told TRT Spor.
"To hear that music makes me excited. I want to win the cup and live those emotions again. Our faith brought us to this level. I have moved one step forward in my football career."
The former Olympique de Marseille man has only scored once since moving to the Turkish champion from Shanghai Shenhua in January, and insists there is room for improvement in his game.
"Even though I am 35-years-old I do still have things to improve. For example, I am not so good at heading the ball," he added.
