Pereira oversaw his first match as Forest manager in the Europa League, and guided them to a stunning win.
Speaking after the game, he said: “We had chance to score two more goals. It was a very good result. It is only half-time, we need to be consistent, the schedule is tight and difficult.
“Everyone must be ready to help the team. This is what I ask them.
“I realised before I came that the players have a lot of quality. They need results but they need to enjoy the game.
“If they enjoy the way they are playing they can have a high level. They need organisation and confidence. I asked them to express themselves on the pitch. They did it.”
