"I respect the beauty of their football. I saw highlights and to go through from the group with Shakhtar (Donetsk) and Inter (Milan) - made two incredible games against Shakhtar.
"All I can say is I want to arrive in the best possible condition when we play them. We will try and arrive in the best condition and best mood possible. We want to compete as best as possible and go through."
