Both the manager will meet each other on Saturday night for the Champions League final.
The two managers faced each other in the Premier League for quite some time when Ancelotti was managing Everton from 2019-2021.
Back in 2018, Jurgen Klopp faced a ruthless Real Madrid side managed by Zidane in the Champions League final.
This year Ancelotti will be attempting to win his second European cup with Real Madrid.
Liverpool manager Jurgen Klopp regards Ancelotti as one of the most successful managers of all time.
Klopp said: “My English isn’t good enough to find a word to describe him, but Carlo for me is obviously one of the most successful managers in the world and a model of how to manage success. A great guy.”
“I have a good relationship with him, but it was paused while he was managing Everton! My respect for him couldn’t be higher. He never stops winning.”
