Langer said if NSW were to seek a flat pitch in a bid to improve their chances of drawing the game, it could end up backfiring badly.
"The great danger for them at Manuka is if they try to keep it too flat, I'm absolutely certain it will start spinning like Mumbai," Langer said.
"We saw it spun on a very good cricket wicket we played on [in Canberra] last week. So if they keep it too flat and they take too much grass off it, I've got no doubt it will spin big time."
NSW were dealt a huge blow yesterday when test skipper Michael Clarke was ruled out due to a fractured shoulder. The Blues will also be without Bollinger, who has been called up for the T20 World Cup to replace Mitchell Johnson.
The Warriors haven't won the Sheffield Shield title since 1999, and are sweating on the fitness of allrounder Mitch Marsh, who is battling a side strain but might play as a specialist batsman.
WA cricket is on a high after winning the T20 Big Bash League and reaching the Shield final.
But Langer, who was appointed coach in November 2012, hopes this is merely the start of something special.
"Winning a Sheffield Shield final would be nice. Winning five or six would be the ultimate."
