The Frenchman was impressed with the Belgium goalkeeper's display in Paris and hopes he isn't in similarly inspired form on Wednesday
Laurent Blanc has admitted he has his fingers crossed that Thibaut Courtois has an off day when Paris Saint-Germain face Chelsea at Stamford Bridge.
The two sides drew 1-1 in the first leg of their last-16 clash on February 17, with the all-important away goal giving the Blues the upper hand ahead of Wednesday's second leg.
It could well have been very different, though, had Courtois not produced several saves to deny Zlatan Ibrahimovic and Edinson Cavani at the Parc des Princes.
The performance of the Belgium goalkeeper did not go unnoticed, with Blanc hoping the 22-year-old has a night to forget in west London.
"Tomorrow we know that we must score at least one goal against Chelsea to qualify. We know that. We have more experience than last year. Chelsea, we know, are better than last year.
"Courtois had a very good game in the first leg. I hope he will be less effective tomorrow night. As it stands Paris will be eliminated. It is up to us to secure our qualification."
PSG went into the first leg under a degree of pressure amid a stuttering Ligue 1 campaign which has seen Marseille and Lyon emerge as rivals at the top of the table.
Since that game, however, Blanc's side have made a marked improvement and sit just a point behind les Gones at the top of the table, with midfielder Blaise Matuidi in confident mood.
He added: "It is necessary that we approach the game with a single goal: to score. I think we are better now than before the first leg against Chelsea."
