Premiership-winning Melbourne Storm halfback Brett Kimmorley has urged Cameron Munster to “trust his instincts” in Saturday night’s do-or-die preliminary final against the Sydney Roosters at the Sydney Cricket Ground.

Speaking to NRL.com, Kimmorley says Munster is the key to a Storm win.

“His kicking game will be very important and even more important than that is his running game because that’s his greatest attribute.

“Rather than just going out there to game manage, I want to see him running the ball on Saturday, using his strength and footwork and trusting his instincts.”
