"We knew [it] was a test against a strong side in good shape and form. It's important to win games like this.
"But that's the past and we must concentrate on the next game against a good team like Everton. But there is great satisfaction at the result and performance.
"We created many chances. It's the perfect game when strikers score and defenders don't concede. The players deserved this, they work hard in training.
"When you see this type of game and commitment from your players, it's fantastic for a coach."
Conte also told Sky Sports: "It's early for us to speak about title contenders. We have to work very hard to continue.
"We can improve a lot. We must improve. After the first part of the season, I can tell more about this run."
