Swedish striker Zlatan Ibrahimovic is Ligue 1's top goalscorer this season, having scored 25 times in the league this season, and 40 in all competitions.
The Chelsea manager told reporters: "They have a team full of fantastic attacking players and goalscorers and that is what really makes the difference in this level.
"The way they play is the way they play. Even against Bayer Leverkusen in the second leg when they changed all three midfield players their philosophy was the same, the positional play was the same and this is a very good quality for a team.
"They have an idea and they go with their idea. We are the same. We are going to play the way we are training and playing and we also believe in what we do."
The teams play the first leg of their quarter-final tomorrow evening.
