Inter won 1-0 thanks to Hakan Calhanoglu's successful penalty awarded for a Mikel Merino hand-ball.
Pavard said: "We managed to work as a team, we are happy. A game of great application and concentration? We played a great defensive game, we didn't concede a goal in the first four games...
"These are 3 important points, now we think about the game against Napoli, which will be equally important."
Calhanoglu also said: "I want to speak in general. Today the game was very difficult, Arsenal are a very strong team. Only the result counts, our defenders did a good job today.
"Today we worked very well and with a lot of sacrifice."
The Turkey midfielder now has scored 19 consecutive penalties and added: "I hope to continue like this, I don't want to make mistakes. I watched the goalkeeper until the end, today he was different."
