Paris Saint-Germain boss Laurent Blanc says the key to beating Real Madrid will lie in keeping "alien" Cristiano Ronaldo isolated.
The Portugal star has scored five goals in just two Champions League games this season and has 11 in 10 appearances in all competitions.
"He's one of the two aliens of planet football. He's good in every area. We have to make sure he has few touches of the ball. We have to keep an eye on him," Blanc said on Tuesday.
"People know our style of play. We like to have the ball. Real are quite defensive but they are very effective. These are two different philosophies that will now meet.
"If they want to give us the ball, we'll take it with pleasure. We meet a European giant tomorrow, but it won't be a decisive match. The decisive matches will come later, I hope.
"PSG are not yet a European giant, but we have the quality and motivation to win."
Angel Di Maria has struggled to hit top form following his €63million switch from Manchester United and Blanc has challenged the Argentina international to improve.
"Di Maria's had an average early part of the season. He's aware of that and he knows he can do a lot better. He's committed to having a great game," he added.
He contimued: "Ibra is coming back. Physically he's really good. I ask him to get involved in the play, which requires a lot of energy. As you get older, you have to train regularly."
"I've read that Javier deserves to play but we have to analyse his early season. Unfortunately for him, and us, he injured his calf and missed three weeks," he added.
"If I were him, I'd have plenty of incentive to prove to everyone that I can be a key player."
