Paris: Casting a long shadow over Paris Saint-Germain’s Ligue 1 date with modest Caen this weekend is the imminent visit to the Parc des Princes of cross-channel giants Chelsea.

PSG square up to Jose Mourinho’s runaway Premier League leaders in the Champions League last 16 first leg on Tuesday, with Laurent Blanc’s side itching for revenge.

Last season, Chelsea blocked PSG’s passage to the Champions League semi-finals on away goals.

“Last year was an apprenticeship, which must not be repeated,” PSG’s Qatari president Nasser Al Khelaifi assured AFP at the draw in December.

At Thursday’s press conference, it was Chelsea inevitably rather than Caen preoccupying Blanc’s mind.

The PSG boss made fun of how his Chelsea counterpart was regarded as, in his words, “a genius” despite their FA Cup knockout at the hands of minnows Bradford.

That Cup upset has given Chelsea crucial more time to prepare for Tuesday’s trip to Paris, with this weekend’s programme in England devoted solely to the FA Cup fifth round.

“As Mourinho is a genius, Chelsea lost their Cup tie 4-2 and everyone thinks that’s fantastic,” Blanc said. “But if the same thing had happened to PSG [in the Cup], it would have triggered a tsunami, or at the very least some turbulence.

“People would have said that the manager didn’t know a thing.”

PSG, who are in the League Cup final and reached the French Cup quarter-finals in midweek, squandered the chance to top the table last weekend when Zlatan Ibrahimovic’s controversial retaken penalty salvaged a 1-1 draw at Lyon.

That left Ligue 1’s defending title-holders in third, level on points with second-placed Marseille and two shy of Lyon.

With Marseille in action on Friday against Reims, and Lyon away to struggling Lorient on Sunday, PSG will be anxious to bag the three points in Saturday’s early game to keep the wheels on their title bid and put them in the perfect frame of mind for Tuesday’s massive European tie.
