WOLVES try king Henry Fa'afili says the squad are not content with the season's work so far.

And the New Zealander will be leading the strike force at Wakefield Trinity Wildcats on Saturday, bidding to build on the foundations laid in the fourth win of the season against Hull Kingston Rovers on Sunday when Wolves did the business with key personnel missing.

Fa'afili, who crossed for his fourth try in three games against the Robins, said: "I think we're going all right, apart from that loss against St Helens, but I speak on behalf of the team and the coaching staff by saying there is always room for improvement.

"We're not satisfied with what we've done so far and we want to keep on improving."

And it is likely that Wolves will have to improve to bring back two points from Belle Vue this weekend, with Wakefield having followed Hull KR's lead and started the new season well.

Fa'afili said: "It was very important to get back on track against Hull KR after the disappointment of losing to St Helens because we want to be top four contenders throughout.

"We produced the right frame of mind against Hull KR. We trained well all week and set goals that we needed to achieve, and I thought we did that exceptionally well.

"Now we have to take the positives and negatives out of the game and prepare for Wakefield, which is going to be another tough game."

Fa'afili recalled last season's trip to Belle Vue when Wolves turned round 21-0 behind and fought back remarkably in the second half to win 22-21 - a Super League record comeback.

He added: "We've got to start how we did against Hull KR, that's strong and fast. I think Hull KR and Wakefield are sides that some teams take a bit lightly but no team can be treated like that in Super League this year.

"We know Wakefield are going to be another tough side to beat."

Fa'afili has had to get used to a few changes in faces around him this year.

The 26-year-old's former New Zealand Warriors teammate Logan Swann is no longer playing on his inside, while the absence of Lee Briers at the weekend meant Vinnie Anderson was linking up on his side of the field.

And then Adrian Morley's injury resulted in Fa'afili switching to the back row midway through the first half against the Robins, which he said was not part of the pre-match plan.

Fa'afili added: "It has taken a bit of getting used to not having Logan on the right with myself, Martin Gleeson and Lee Briers but we do have a lot of talent and depth in the side.

"I think Benny Westwood has been playing outstandingly well so far on the right. He's stepped up to the role.

"It wasn't really part of the plan for me to move into the pack on Sunday but I'm professional and adapted to it.

"I like going into the middle into the rough and tough stuff. That came about with Adrian Morley going off and Richie Barnett coming on, and that's the kind of depth we have now.

"I thought we showed a lot of character with the new halves and then losing Moz.

"Overall, the team's pulling together and gelling together and I think that's the key ingredient we need to keep on winning games."
