The former Spain and Barcelona head coach added: "They have one of the best attacks in Europe, we're going to look to keep the ball, but we'll need to be careful with their counter-attacks, they've got three fighter jets up front. We have to be able to do what we've been doing since the start of the season, there's nothing that changes.
"We know that we're facing the most consistent team this season, but the plan doesn't change. It's going to be a hard-fought, difficult game. The first match is not going to decide everything, but it's a very important one for us. It's hard for opponents to play at the Parc des Princes with the pressure of the crowd."
