"He's a great Coach who likes to play good football and his teams play with real style," Pirlo told Marca.
"Ancelotti was a good choice for the clubs he has coached because he has a good footballing philosophy.
"I have nothing but good things to say about him, he's a friend. He's an outstanding Coach, who treats his players well and is well-liked inside the dressing room.
"Will he go? I don't know if he's going to Real Madrid or staying at Paris Saint-Germain. Carlo is a friend, a great person and I wish him all the best, wherever he is.
"He's an amazing Coach, I was very happy playing under him and we'll just have to wait and see where the future takes him.
"Real Madrid is a great club and I'm sure that one of Carlo's dreams is to work there."
