Sagna hopes City can get on the front foot as they face a side who, like them, have opened the season with three successive Premier League wins.
He said: "I would say it is one big test from many we are going to have this season.
"It's a really good team, a strong team.
"They have new players also and have had a great start, the same as us, but we want to stay on the top now until the end. We learn from last year and are going to try to dictate the game."
