THE Wire will have to play even better than they did in the semi-final win over St Helens if they are to beat Wigan in Saturday's Super League Grand Final.

That is the view of centre Bryson Goodwin, who has had stellar first season in England since joining Wolves from South Sydney Rabbitohs.

New Zealand international Goodwin won an NRL Premiership with Souths in 2014 but did not play in the Grand Final and he says The Wire have the right mentality to triumph at Old Trafford.

However, he says they cannot afford to give the Warriors "any little chance" on Saturday night if they are to win their first ever Super League title.

"We fully believe in each other as a club. We know what we have what it takes," he said.

"We wouldn’t be here otherwise and that’s the same for Wigan.

"They’ve given us a few beatings and we know if we give them any little chance, they will put points on us very quickly.

"Their defence is great too, so we’re going to have to be really, really good.

"No-one gave us a chance (against Saints) outside of the club.

"We knew what we could do, we had no pressure on us and we performed the way we know we can.

"That’s the way we’re probably going to have to perform on Saturday. We’ll probably have to be even better."

While he did not add to his impressive tally of 16 tries for The Wire in the semi-final, Goodwin did provide two key assists for wing partner Tom Lineham.

The 32-year-old is happy with how his partnership with the man affectionately known as "The Flying Pig" has developed over the season and claims his two tries were among the best finishes he has seen this season.

He also says the atmosphere has been "joyful" within the camp throughout the week –a demonstration of how the team has bounced back from their Challenge Cup Final defeat to Catalans Dragons at Wembley.

"The two tries Tommy scored were unbelievable," he said.

"They may not have been flashy ones in the corner but they were fantastic finishes.

"I think they were two of the best finishes I’ve seen this year.

"We’ve been together for most of our matches, so the partnership has come with time.

"That’s how it has been throughout the squad. We started a bit slow this year but with time we’ve got better.

"The atmosphere in camp has been joyful. Everyone is pretty happy and is looking forward to the occasion.

"Pricey and the coaching staff will keep the mood happy and keep us calm.

"We’ve forgotten about Wembley. It’s done and dusted.

"We didn’t perform that day but we’ve moved on well."

Goodwin had members of his extended family over in England to watch him play at Wembley, but he says it will just be his wife and children in attendance this time.

However, he is sure the Goodwin clan will be watching on from Down Under.

"It was too short notice to bring people over, but they will all be watching on TV at home," he said.

"It’ll be a pretty late night for them, but they will get to see it."
