"Being champions is a new position for us to be in but the culture we have means there's no chance of complacency or taking our foot off the pedal,” Corbisiero said. “It was great to win a first championship but we can’t afford to let off if we want to build on that success.
"It's such a competitive league – there are so many teams that have a realistic chance of winning it.

"It should be an exciting year for the club."
