Penrith's No. 6 jersey will be contested when Jett Cleary joins the club for pre-season training.
The youngest Cleary is widely expected to leave the New Zealand Warriors after securing an early release.
That move follows his successful NRL debut for the Warriors last month and would place him alongside brother Nathan at Penrith.
Jett's long-term ambition is to partner Nathan in the halves, but his family connection will not guarantee selection.
Former teammates and players expected to join him at Penrith believe he is prepared to compete for every minute.
Their observations also identify a quality that separates Jett from Nathan, while making clear that the younger brother faces a significant challenge for the six jersey.
His arrival will also shape the future of another Penrith player and place him under father Ivan during Ivan's final year in charge.
Jett's development, his expected move from the Warriors and his prospects of earning selection will be central to the next stage of his career.
