Chelsea lost 2-1 at home on Friday night.
"Every single game is very tough and we mustn't forget last season. That's important because it was a bad season and I don't want to repeat that. When you finish in 10th place it's something strange, it's not natural or simple. It means we have to work very hard to improve," said Conte.
"I'm guilty because I'm the coach and it means I have to work more. We must feel the danger in every single moment of the game if we want to win and think like a great team. We must pay attention and be focused."
He also stated: "In the first half, I must be honest, I think we gave away two goals.
"The first goal came after a free-kick which they took very quickly and the second after a throw-in. From long distance it was a great goal but when you give away two goals in that way its very difficult.
"These are tough games and I think you must pay attention in every moment, every single minute of the game, because that makes the difference. In this case we paid because after the first half we were losing 2-0 and then it's very difficult.
"In the second half we scored the goal and then missed a chance to draw level through Costa. We had some chances to draw but it was too late."
