NRL: Mitchell Moses tears up Wests Tigers to christen Bankwest Stadium

Brad Arthur is unwilling to declare Parramatta have turned a corner even after their Mitchell Moses-inspired 51-6 flogging of the Wests Tigers to christen Bankwest Stadium.

The Eels were superb in the nine-tries-to-one rout as they recorded their biggest win under Arthur's coaching.

Arthur's future has been a hot topic of conversation in Sydney's west as he comes off contract at the end of the year.

After finishing with the wooden spoon in 2018, the club had planned to hold off talks until June.

While he has made no secret of his love of the Eels and his desire to stay, Arthur said that even with his side at 4-2 and in fifth, he hadn't done enough to earn a new deal.

He was unwilling to talk his side up as top eight contenders and said they still had a lot of improvement in them.

"I've got to earn my contract," Arthur said.

"But it's not about me, it's not about (off-contract skipper Clint Gutherson). It's about the team. We've just got to play well."

Even without talisman Blake Ferguson (ribs) and after losing prop Daniel Alvaro to a head knock in the first tackle of the game, they overawed Michael Maguire's side with an inspired performance.

It was the perfect start to life at their new $330 million home, putting in arguably their best performance in years.

"I didn't see that scoreline coming," Arthur said.

"We haven't made a habit of performing on the big stage and there was a lot of pressure."

The game was as good as over after the Eels opened up 30-0 lead after 31 minutes thanks to some Moses, Clint Gutherson and Michael Jennings magic.

Moses etched his name in the Eels' history books when he ran 70 metres off a Gutherson break to score the first try at the new stadium.

Moses finished with 19 points and three try assists after setting up four-pointers for Brad Takairangi, Oregon Kaufusi and Reed Mahoney before sealing the win with a field goal.

In the first five rounds the Tigers only conceded 59 points but on Monday their middle forwards were badly beaten and made to pay for some lazy defence.

The joint venture lost influential hooker Robbie Farah to a head knock in the ninth minute, prompting a reshuffle which saw fullback Moses Mbye move into dummy-half.

Maguire revealed Farah had passed his head injury assessment test but because he showed signs of being unsteady on his feet, he was not allowed back on by club doctors under NRL concussion rules.

"He was actually right to go back on," Maguire said.

"It was just unfortunately due to the ramifications, the stipulations around concussions, he couldn't go back out.

"He'll have no problems at all (playing next week)."
