It is naive to assume that Real will play defensively in this pair and will give PSG a lot of chances to score.
Why it is naive? It is my prediction, I consider how Real Madrid should deal with PSG strikers. I think Real Madrid coach may consider about this. Focusing in defending doesn't mean Real Madrid stop attacking and has no intention to control the match. What I mean, those defenders must be more discipline and more strict to keep PSG strikers. You are misunderstood, I never state that Real Madrid players to let PSG players be easier in attacking.
Against PSG which has a lot of great strikers, it would be a mistake if madrid prefers to stay, even though madrid are in pretty good form at the moment, but you mustn't forget that madrid's defense is still very bad, I think whoever scored first in the match will dominate the game, and I think madrid will play aggressively in that match so as to put pressure on PSG players, sometimes attack is a good defense in football.
