However, Pereira was keen to stress that les Parisiens have a wealth of quality across the park, and highlighted the size of the task ahead for his side.
“PSG are a very good team with some very good players,” he told reporters. “We have to be extremely focused if we want to get a result.
Pereira also spoke about PSG's excellent league form, and the money they have spent to bring the best players to France.
“They have spent a lot of money over the past couple of season and that shows with where they are in the league.
“It's going to be a great game.”
