Pereira believes that his Porto team will try to impose their own style on the in-form French outfit in an intriguing tie.
He told reporters at the pre-match press conference: "We're not going to worry only about Ibrahimovic, because there are 11 players in a team and PSG have a great side, individually and collectively.
"But they'll be up against a great team too. The last match in Zagreb left only good memories. The team showed great tactical maturity and our identity was expressed throughout the match.
"We prepared for this game as we always do, passing information to the players as usual. We will play as we do all the time, controlling the ball."
PSG and Porto are joint-top of Group A after winning their opening fixtures, against Dynamo Kiev and Dinamo Zagreb respectively.
