PSG must overturn a 3-1 deficit this week in Paris.
"It [the first leg] was not a game between players and players, there were influences from outside," he said.
"I don't want it to be an excuse, but everyone felt that way, for me it is a lack of respect for Paris, for France...
"But it's not just about this game, it was the same last season.
"This is an important question: why is this happening?
"We had a 44-year-old referee with no experience (Rocchi), in what was supposedly the game of the season.
"If that's the case, then we need one of the best referees and we want to have someone of an exceptional level."
