Mancini is amazed at Zidane's achievement in leading Real to the Champions League title at first attempt.
He remarked to Corriere dello Sport: "What he has done is phenomenal.
"He successfully managed to perfection arriving in a massive club and I think this is because of all the experience he could store when he was a player.
"I do not know if he can repeat the feat this year. Anyway, it is certain that with (Cristiano) Ronaldo and the others, they are definitely a candidate for the title."
