With Jonathan Sexton now plying his trade at Racing Metro in France, Ian Madigan will be asked to step up and fill the Ireland fly-half's void at Leinster.
The 24-year-old made 32 appearances for the Amlin Challenge Cup winners last season, whilst also racking up four Ireland caps.
New Leinster head coach Matt O'Connor has already challenged Madigan to step up to the mark and fill the big shoes left by Sexton.
He proved himself to be a more than capable deputy last season during the first-choice out-half's spell on the sidelines - but can he take over Sexton's mantle on a full-time basis?
Well, Madigan ended the season as RaboDirect Pro12's most efficient goal-kicker.
The Dublin-born star, who missed out on a place in the British and Irish Lions squad this summer, extended his Leinster stay until 2016 earlier this week, penning a €750,000 deal.
O'Connor said: "We are delighted that Ian has extended his stay with Leinster," he said. "We are confident that his best years are ahead of him and he can achieve even greater things in the years to come."
Keeping the Leinster fly-half on his toes will be back-up Jimmy Gopperth, who joined the Irish province this summer.
Seeing how Madigan progresses as he emerges from the shadow of Sexton makes him a player to watch in the Pro12 this season.
