The Ligue 1 champions have invested heavily in their squad over the past three years and reaped the rewards by winning two league titles.
However, despite their increased exposure internationally and domestic dominance, PSG have not been past the quarter-final stage of the UEFA Champions League, losing at the quarter-final stage to Chelsea on away goals last season.
Blanc knows the Parisian outfit cannot afford to repeat that in the Champions League and urged his side to show that the club can compete with Europe's elite both on and off the pitch.
"I think that Paris Saint-Germain are increasingly recognised in Europe," the coach said at a media conference on Tuesday. "Now we need to prove it on the field and I am sure that on Wednesday it will not be easy.
"This first meeting is important, because it will determine much the rest of the adventure.
"In the Champions League, as the competition progresses, the harder it is to score goals.
"We need to know the score and manage to learn from our last match in Rennes [when they drew 1-1]."
