The Bianconeri have one foot in the Quarter-Finals of the Champions League after this first leg triumph in Scotland.
"It was certainly a very important victory. I personally as a player have been in this competition for many years, but had rarely seen a passionate atmosphere like this," said Conte.
"At the start the Celtic players went above and beyond their capabilities, but we held out under their pressure. The moment they dropped the tempo a little, we got our goals and created more dangerous opportunities.
"It wasn't easy to play in that atmosphere, and I can say that as someone who has experienced these things as a player. I couldn't communicate with the players because it was so loud.
"Every time there was a corner, it felt like the stadium was coming down. The lads deserve praise for getting this result in Glasgow."
