The French giants forced a 2-2 draw with late goals at Parc des Princes in the Champions League quarter-final first leg on Tuesday night and are now faced with the unenviable task of overcoming the Catalan powerhouse at the Camp Nou next Wednesday.
"In the first half, especially in the first 10 minutes, we had a few very good chances and if we'd have put one of those away it might have been different," he said.
"Then obviously they got their goal, then it was an uphill battle, but I think we deserved the draw.
"It's better than it was at 2-1. We go there, it's going to be difficult but there's no reason we can't go there and get a result."
