The Old Lady confidently disposed of the European Champions with an emphatic 3-0 scoreline in Turin on Tuesday.
"It was a test of strength and perhaps Tuesday night's match was the best of the Conte era," the defender told Juventus Channel.
"The Chelsea game was the most important encounter of the season so far. We knew we couldn't slip up and played a great game. But in order to go through we'll require an even better performance.
"The disappointing thing is that you can only enjoy that kind of victory for an evening, because the following day you're already thinking about the next fixture, even more so considering it's Milan."
