City travel to the King Power Stadium to square off against Leicester on Tuesday night and the match is set to provide a stern test for the visitors.
Sagna is well aware of how good a side the Foxes are and has urged his teammates to be wary of the attacking threat posed by Claudio Ranieri's men.
Sagna said: "But now Leicester is a massive game but we have to show our strength.
"I am not surprised by Leicester because they have quality players, we could see that last season. They play as a team, they fight as a team, they are dangerous and hard to beat.
"I heard about Riyad Mahrez in France when he played for Le Havre. He is a top quality player. He has the level to play for big teams. He enjoys playing and he doesn't think too much - he is instinctive."
