For a player who thrives on making the unexpected happen on the football field, Melbourne Storm fullback Ryan Papenhuyzen has a surprisingly rigorous schedule of pre-game routines and superstitions.

The 21-year-old has risen from the club's third-choice fullback at the start of the season to their starting No.1 and one of their most dangerous attacking threats.

He has kept the same pre-game menu and practices right up to this Saturday night when his side will play the Sydney Roosters for a place in next Sunday's NRL grand final. One recent addition is his moustache.

"I'm due for a shave, but will keep the mo as it's good luck," Papenhuyzen said with a smile this week.
