The 53-year-old is expecting a tough examination in his side's last 16 Champions League encounter against resurgent Los Che side on Tuesday evening
The Parisiens go into their last 16 Champions League encounter without Thiago Motta and Thiago Silva and the Italian is expecting a stern encounter against quality opposition.
"I do not think we are favorites for this game, we're playing against a team who are very well organised and have very good players," he told reporters at a press conference.
"Both teams are currently in good form. I think it will be an open game. I don't think it'll be a physical game, but tactical.
"We need to show the qualities of character and personality in this type of game. I hope we will do the same thing like we did against Porto.
"The absences of Thiago Motta and Thiago Silva are important but Alex and Mamadou Sakho fared well in recent matches. This team is great because we can do without players like Silva or Motta."
PSG striker Ezequiel Lavezzi also refused to be drawn into a debate as to who was the stronger of the two sides and said he was merely focused on ensuring his side put on a quality display.
He added: "Everyone says we are favourites but we're not, we don't think like that. We just try to play good football.
"This match must be played, we did not win in advance."
