Whilst respecting Chelsea and their squad, Lavezzi does believe that they will the ones to progress into the last four.
"Chelsea are a big team but it did not matter who we drew: we don't fear anybody," said Lavezzi.
"We have to respect Chelsea of course because they have a successful coach and very good players but now, if you ask me who are the superior team, then I have to say PSG.
"We have built one of the strongest teams in the world and we feel that now this is our time.
"PSG has now arrived at a level where anything is possible. We are at a level where we attract the best players in the world, where we can beat any team in the world, and of course where we can win the Champions League."
