While Parramatta fans everywhere jump on board the "Hayne Train", Eels captain Nathan Cayless believes 108kg wrecking ball Fuifui Moimoi should be the man credited with reviving the club's fading NRL finals hopes.

Pin-up boy Jarryd Hayne was simply outstanding as he tore Penrith apart in Saturday night's amazing comeback win.

According to Cayless, it was only made possible thanks to the work of the forwards led by a reinvigorated Moimoi.

Dumped to the bench in a clear message from Eels coach Daniel Anderson that he was not happy with the Kiwi international's form, Moimoi produced his most potent display of the season capped by a bullocking try which left defenders sprawled.

"To be fair I thought the man that changed it around for us on Saturday night was Fui when he came off the bench," Cayless said, with the Eels turning around a 22-0 deficit to run out 34-28 winners.

"He wasn't too happy being put on the bench. He was running like a man possessed and that try he scored was one of the best I've seen from a front rower.

"He was the one that really got us going on Saturday night."

Ironically Moimoi's 33-minute effort against the Panthers was his lowest of the season but what he lacked in quantity he more than made up for in quality.

It was the Moimoi of 2009, the man who along with Hayne carried the Eels to the grand final as he ended the season rated the best big man in the game.

He really put on some big hits and really turned the momentum, he turned the tide for us," Cayless said.

"He and Tim Mannah got us some room for Haynsey to do his stuff."

Moimoi has been reinstated to the starting line-up for Friday night's tussle with Canterbury at ANZ Stadium but given his effort off the bench against the Panthers, it would be no surprise to see him again left on the bench.

The only drawback could be the effect the switch had on Justin Poore, who produced one of his worst attacking effort of the season.

After clocking up 176 metres and 131 metres in two of his last three starts, Poore ran for just 70 metres from eight runs in 46 minutes of game time.
