The Blues found themselves 2-0 down to Leicester City in the third round of the EFL Cup at the King Power Stadium before powering back to win 4-2, thanks to an extra-time double from Cesc Fabregas.
"It was a typical English game," Conte said.
"It's incredible that after 30 minutes you are 2-0 down and then have a great reaction to score four goals and to go in the next round.
"If you ask me if I'm happy with the goals we conceded, I am not happy, but I saw a great reaction from my players and my team. This is very important because they showed a great heart and a will to win and go in the next round. It wasn't easy at 2-0 and after a defeat in the last game in the league.
"We know that we can improve, I repeat this. The only way I know is to continue to work very hard and to improve on different aspects. I am sure we can improve and I will try with all my strength to do this."
Gary Cahill and Cesar Azpilicueta responded for Chelsea after Okazaki's earlier double, forcing the game into extra-time, before Fabregas fired home twice in quick succession in the 92nd and 94th minutes to send the West Londoners through to the fourth round.
