The experienced coach is looking forward to the quarter-final tie versus the Catalan powerhouse and expects a tough test
The Ligue 1 leaders are one of the rising forces of European football following the arrival of stars such as Ezequiel Lavezzi, Zlatan Ibrahimovic and Thiago Silva in recent years, and have made it to the final eight of European club football's elite competition for the first time since 1994-95.
"We all realise that it will be a very difficult tie, but it will be a good test for us to see where we stand," Ancelotti told reporters.
"We put in a good performance against them in a friendly in pre-season. The atmosphere will be completely different, though.
"Barcelona have a lot of experience and quality, but we will try to play our own game.
"It's not a disadvantage that we play the first leg at home. We will have to remain focused for the full 90 minutes and will need all our energy."
The first leg in Paris will be played on April 2.
