Manchester City have been handed a two-season European ban by UEFA for breaching Financial Fair Play regulations, though the English club will appeal the sanction at the Court of Arbitration for Sport.
Asked for his thoughts on what has happened to their Champions League opponents, Real Madrid coach Zinedine Zidane said: "I don't really know what's going to change or what's going to happen. I can only talk to you about football and about games we're going to play.
"They are a very strong team, very competitive team and this is something that is not going to change. But right now I'm focused on our game tomorrow.
"They are a great team regardless of the situation they are going through. The games against them in the Champions League will be tough.
"As far as the ban goes, I cannot talk about that, it's not my job. What I want to stress is Manchester City are a great team, a very tough opponent."
