Sunday’s grand final will be Melbourne’s Marike Koroibete’s last in rugby league before joining the Melbourne Rebels rugby team.

The Fjijian flyer admits the decision to defect to the rival code came down to money and money alone.

“I’d like to have stayed,” Koroibete said.

“I have to look after the family, especially back home (in Fiji).

“It’s a business decision; but if they gave me a good offer I would have stayed.”

Koroibete, now a cult hero at AAMI Park, admitted that playing his final home game with the Storm was difficult.

“Even today (last Saturday) was a bit emotional, playing my last home game,” he said.

“Playing in the grand final next week will mean a lot to me.”
