Benzema knows the size of the task that awaits Real Madrid in the Champions League last 16.
"What I can say about City is that they're a good team with a very good coach [Pep Guardiola]," Benzema told UEFA.
"[They're] a team that play with the ball, who aren't scared to make lots and lots of passes.
"It's going to be an even game."
Benzema will make his 100th appearance in the Champions League against City on Wednesday and he knows how special the competition is.
"I'm really proud, especially as it's the Champions League, which is something different," he said.
"It's not the same as the league or other competitions.
"I think that everything around it is a little crazier, there's a little more pressure.
"To get to that 100th game, I hope I'll be there, operational. I'm going to enjoy it.
"[The Champions League] represents a lots of things.
"As I've said, there's something different [about it], the emotions are not the same. That comes automatically in fact.
"It's not that you don't give as much in other competitions, but in the Champions League, I don't know... there's something about it."
