The NRL premiership decider may well go down to the battle of the coaches.

Minor premiers Melbourne take on early season favourites Cronulla on Sunday evening in one of the most anticipated Grand Finals in recent years.

Four time premiership winner Steve Renouf says despite the presence in the Storm side of Cameron Smith and Cooper Cronk, it will be the leadership and experience of Melbourne coach Craig Bellamy (pictured), with five Grand Finals under his belt, that will be the difference in the end.
