Ranieri blasted: "His words really annoyed me, as usually these things remain within the locker room. I feel betrayed by him as a man more than a player, and that is the worst thing.
"Trezeguet touched the ball six times in the first half and six in the second, which included a great assist and a header. When I saw we couldn't get round Chelsea any more, I introduced Amauri, who is Juve's top scorer.
"I let Trezeguet play for 80 minutes in the most important game of the season. I've always held him in high esteem, but maybe he didn't do the same for me."
Juve president Giovanni Cobolli Gigli stood by Ranieri, declaring: "Like everyone in our team, he wants to play, but he will stay at Juve because he has a contract and is one of our four star strikers.
"As for Ranieri, he will remain and continue working with [general manager Jean-Claude] Blanc to build an even more competitive squad.
