PSG coach Laurent Blanc hopes they can find a way through Chelsea goalkeeper Thibaut Courtois tonight.
PSG go to Champions League opponents Chelsea, with the scores locked at 1-1.
"It is true that in the first-leg, he had a very good game. But the question is tricky," said Blanc.
"If I answer frankly, if Courtois has a great game it means that PSG dominates and creates opportunities! I want him to have a great game, but for PSG to score goals!
"If he had let those goals in, we'd be in a favorable position today, as our team was superior to that of Chelsea (in the first-leg)."
