Clayton Faulalo scored eight tries in 14 appearances for Manly last season, and is widely expected to play a major role in 2027.
His breakout campaign, during which he filled almost every backline position, helped earn him selection for Samoa at the 2026 Rugby League World Cup.
Faulalo made his international debut late in Samoa's semi-final defeat to the Kangaroos, after serving as an unused reserve against France, Papua New Guinea and Tonga.
He is the latest Sea Eagles player to represent Samoa, following Martin Taupau, Frank Winterstein and Josh Aloiai.
Faulalo and several other Manly players involved in the World Cup are due back for pre-season training in mid-December.
