Parramatta have landed a big coup by extending the contract of Semi Radradra until the end of the 2018 season, handing the try-scoring sensation a huge pay rise in the process.

The former Fijian rugby sevens player had been the target of overseas offers from the 15-man code but the Eels have been desperate to retain the 21-year-old, who has gained a cult following since making his NRL debut late last season.

Eel deal: Semi Radradra has signed a three-year extension with the Parramatta Eels.

The club on Tuesday finalised a new long-term contract for Radradra, who was contracted to the blue-and-golds until the end of next year but is now set to be part of the furniture at Pirtek Stadium for at least the next four-and-a-half years.

Called the ''Semi-trailer' by fans, Radradra tops the NRL try-scoring tally with 11 so far this campaign for Brad Arthur's team, who are running seventh after 12 rounds despite a 38-12 defeat to Penrith last Friday night.
