The Blaugrana and the Ligue 1 champions are expected to cruise into the last 16 but the former Spain international is refusing to underestimate the threat posed by Ajax and APOEL
The two sides met in the quarter-finals of the 2012-13 tournament, with the Blaugrana scraping through on away goals.
Most pundits believe that the pair wil cruise into the last 16 of this season's competition, having been drawn in a group alongside Ajax and APOEL, but Zubizarreta is not understimating the threat posed by the supposed 'underdogs'.
"When you come to this draw, you know you are always going to be drawn against a big team," the former Barca goalkeeper is quoted as saying by his club's official website.
"If you get over-confident, any team in the Champions League will make it hard for you. We’re going to be facing three very different styles of football
"We’ve played PSG before. It’ll be a great game. They’re a great team both in terms of individuals and as a unit.
"But this group isn’t just about PSG. Ajax have shown us before how good they can be. APOEL fight hard.
"Some very big teams have already found out just what a difficult opponent they are in Europe.
“These are games where every team has the right to dream. We have our dreams, and they all have their own."
