The Blues came back from a goal down to defeat Diego Simeone’s side 2-1, with Michy Batshuayi scoring at the death to secure all three points.
Conte said: “A good performance of my players and I am very happy. We must be pleased for the performance, the personality and the right spirit we showed tonight against Atletico Madrid,” he said.
“We went 1-0 down after the first half and it is very difficult when Atletico Madrid score to come back, but despite this we deserved to win. We continued to play with a good personality, kept our heads on the pitch in every moment of the game and we deserved to win against a really good team.
“I try to repeat to my players, to play at home or away doesn’t change, we must always play with the same personality and desire to play football and try to win.
“I think we are trying to do this. Last season we did this very well and won the league and reached the final of the FA Cup. Now we have this possibility to play a great competition like the Champions League and our mentality doesn’t change.
“This was a really big game for us and to play in this way means we are working very well. I am very pleased for my players because they deserve to play this type of game, above all to play in this way.
“You can win but if you only defend and counter-attack I think there isn’t the right satisfaction. Instead to try to play and show we are ready to play, it’s very important. The answer tonight was very positive.”
