Paris Saint-Germain can overturn Barcelona deficit - Zinedine Zidane

Paris Saint-Germain could still reach the Champions League semifinals despite needing to score at least three goals at Barcelona on Tuesday, according to France legend Zinedine Zidane.

PSG's 3-1 first-leg defeat in the French capital last week gives them only a slim chance of progressing at the Camp Nou, with Laurent Blanc's men set to fall at the last eight for the third successive season.

Zidane acknowledged his former international teammate faced a stiff challenge in Catalonia but insisted it was not an impossible one, particularly with the return of Zlatan Ibrahimovic and Marco Verratti from suspension.

"It'll be very difficult for PSG to score three goals at the Camp Nou, but they're a team that's capable of doing it," the Real Madrid reserve team coach told media ahead of Monday's Match Against Poverty in Saint-Etienne.

"They have the players to do that, and they are also going to get certain players back. So, in a single game, anything is possible. It's certainly the most difficult challenge they face.

"But as everyone thinks they won't go through, it's at those times that players are capable of anything. I hope for them that they'll have the possibility to worry them."

Zidane cited the example of his part as an unheralded member of a Bordeaux side that shocked a star-studded AC Milan in the UEFA Cup quarterfinals in 1996, before going on to finish as runners-up.

"I remember when we played against the great AC Milan with Bordeaux," he said. "We lost the first leg 2-0, and we won 3-0 at home. It was the great era of Milan with [Franco] Baresi, [Paolo] Maldini et al. We weren't very much at all, and in the end... It's not the exactly the same because there are already established players in Paris, but anything is possible over one game."
