The English side drew 1-1 against Barcelona at home, and now face a return leg at the Camp Nou in two weeks time.
Conte will be hoping his team are ready for the game, as there are many possibilities that will see them through into the last eight.
"You have to respect the opponent and, in this case, when you play against Barcelona, you know very well that if you want to face them box to box you are crazy, you are going to lose the game not only 1-0 or 2-0, but 4-0, 5-0 or 6-0. You must use intelligence," he said.
"We are trying to build something important with a lot of young players, and when you have young players you need experience. For this reason you must play an intelligent game, we are not stupid."
