PSG ran out 4-1 winners in Piraeus back in September but the coach insists it was a tough night's work and is expecting it to be no different in Wednesday's Champions League clashParis Saint-Germain boss Laurent Blanc is expecting a stern test from Olympiakos after revealing the difficulties his side faced in the first half of their 4-1 Champions League win over the Greek side in Piraeus.
Back in September Edinson Cavani opened the scoring, but an equaliser from Vladimir Weiss saw the game remain at 1-1 until the final 22 minutes, before two Thiago Motta headers and a Marquinhos goal secured victory.
Les Parisiens are yet to taste defeat in any competition so far this season, but Blanc is wary of the threat posed by Wednesday's visitors.
"In the first game they tried to surprise us by pressing us in midfield and playing higher up, because they know that's where we are competitive," he told reporters.

PSG left-back Maxwell was also quick to highlight the qualities of Olympiakos, but stressed the improvement in Blanc's men since the opening weeks of the campaign.
"Now things are different. We control games better," the 32-year-old added. "But Olympiakos have players of great quality and their coach Michel is well known in Spain. They can create problems but we must be confident at home."
PSG top Group C on 10 points ahead of the game, with Olympiakos three points further back in second spot.
