Departing NSW Waratahs winger Alofa Alofa has declared he’ll throw his much smaller body on the line to try and stop rampaging Crusaders powerhouse Nemani Nadolo in Saturday’s Super Rugby final.

Former Waratahs winger Nadolo, who moved to Queensland from Fiji when he was a baby, has emerged as yet another strike weapon for the perennially powerful Crusaders.

The Australian under-20 and Fijian Test representative’s tally of 11 tries leaves him just one behind competition leader, Waratahs fullback Israel Folau.

If the teams line up for the final as they were listed for their respective semi-finals, the job of marking Nadolo will fall to Alofa.

Slated at 1.94 metres and 125 kilograms, Nadolo is almost 10 centimetres taller and more than 30 kilograms heavier than Alofa, though the Waratahs speedster joked the differential may be closer to 50.

“I’m going to throw my body on the line and put it in for the team, if I do get picked this week,” said Alofa, who will join French club La Rochelle after completing his Waratahs commitments.

Asked what the key was to felling the giant, Alofa said “close your eyes and just aim for his legs.”

Nadolo’s success has come as no surprise to Waratahs No.8 Wycliff Palu, who said the winger was a close friend, who he stayed in touch with via social media.

“I think he probably was unlucky to not get an opportunity here and he’s been going really good,” Palu said.

“When he left here, he’d had a really good pre-season with us and I think he scored four of five tries in one of the trial games, so it doesn’t surprise me what he can do.

“I think it’s just about getting an opportunity and really taking it.

Like Nadolo, Alofa has been a valuable addition to his team’s backline stocks, scoring several important tries.

The only starter in the Waratahs semi-final side not to have played Test rugby, Alofa has been grateful for the chance to play for NSW.

“(They are like ) A band of brothers basically,” Alofa said.

“I’m grateful that I’m even playing alongside the likes of Wycliff and (captain and openside flanker) Michael Hooper.

“I didn’t think I’d be in this position, but I’m humbled by it.”
