Postecoglou's future has been called into question on the back of successive Premier League losses, seeing Spurs slip to 12th in the table.
Many have criticised the Australian's stubbornness with regards to altering his attacking style of play, but Pereira believes he should stick with it.
"I love it. I appreciate it a lot because we competed against each other in Asia," Pereira said. "He is a manager with different ideas.
"He has very offensive ideas and it means they are a team that can score a lot of goals.
"We need to be at our best level to compete with them. The game will be very hard for us."
Pereira is aiming to become the first Wolves boss to win his first three matches in the top flight, having so far beaten Leicester City and Manchester United since succeeding Gary O'Neil.
Those wins have lifted Wolves out of the relegation zone, while Spurs are now 11 points adrift of the top four after losing to Liverpool and Nottingham Forest.
Tottenham is without at least eight players for the home clash with Wolves, but Postecoglou is bullish heading into 2025.
"Our league position is not great but it's super tight and we're not that far off," he said. "We're in the semi-final of the Carabao Cup and still in a great position in Europe and there's also the FA Cup.
"There's still everything to play for. For us this year to make it a season where we can have success, but we need some help.
