Petrovic's comments come after Urawa have endured a disappointing AFC Champions League campaign as they now sit at the bottom of the Group G standings with only one point.
However, if they were to beat Suwon, their dreams of qualifying for the knockout stage of the tournament will still be kept alive.
After losing their first three games, Urawa drew 1-1 with Beijing Guoan on April 8 to end their unbeaten streak.
With that in mind, Petrovic has called on his side to go one step further and register their first AFC Champions League win of the season.
"Unfortunately the last match (against Beijing) ended in a draw and now we are in a very tough situation," he told the official AFC website. "We still have a slight chance in the AFC Champions League though, so we have to win against Suwon and we will play with our full power right from the beginning.
"Suwon are a fantastic team in good form now so I think the game will be very difficult. We will attempt to score as many as possible and try hard not to concede."
However, Suwon head coach Seo Jung-won believes that his side have the upper hand since they beat Urawa 2-1 on February 25.
But, he added that Urawa will be a very dangerous side since they don't have anything to lose and are currently atop the J League standings.
"We won the last match against Urawa, but now they are in the first place in J League, so it will be very tough game," Seo said. "When we played that match in February, both teams were not in a good condition because our domestic seasons were just starting. But now, the situation has changed and I promise you to a fantastic game.
"You never know what will happen in football matches, but I hope we can get all three points."
