Arsenal manager Arsene Wenger is of the belief that Paris Saint-Germain have the ability to beat Barcelona in the Champions League quarter-finals.

The French giants host the Catalan stars in Paris in the first leg on Tuesday and Gunners boss Wenger feels the Blaugrana could perhaps be a touch vulnerable after some shaky performances earlier in the competition, giving PSG the ascendency.

"Seeing as Celtic and AC Milan have managed to beat Barcelona, anything is possible for a team like Paris Saint-Germain," wrote Wenger on his Eurosport blog.

"Barcelona are not invincible. It's clear that Barca are the superior side technically, but they have lost a bit of spark recently.

"They [Barcelona] are now more vulnerable at the back and I believe that PSG have enough attacking potential to exploit this vulnerability which did not exist in previous seasons."
