Wendell Sailor believes the Warriors' loss is St George Illawarra's gain, after hooker Nathan Fien helped the Dragons brush aside his former teammates 29-4 in Sunday's NRL clash at Mt Smart Stadium.

It was Fien's first appearance against the Warriors since joining the Dragons last month after being dumped to reserve grade by coach Ivan Cleary earlier in the season.

Sailor said he's been impressed with Fien's performances in his first two games for the Dragons.

"Full credit to Nathan Fien," said veteran Dragons winger Sailor.

"The way he came in, you can tell class players. I'm not sure what he did here at the Warriors, but I just love the way he's handled himself the last couple of weeks.

"He's been great for our squad."

Sailor admitted he was surprised the Warriors allowed the 29-year-old former North Queensland rake to leave the club.

"To be honest, I'm a football fan and I was surprised," the former dual international said.

"I'm not sure what he did, but he's too good a player to be playing reserve grade.

"Someone's loss is our gain. I'm pretty sure that Fieny is going to be a big part of what we do this year."

While the Dragons, moved four points clear at the top of the NRL table following their comprehensive victory, former Broncos star Sailor said he isn't thinking about the possibility of winning a fourth grand final.

"At this club we don't delve into that," he said.

"As much as I've been there before and done it, Wayne [Bennett] is not big on it.

"Even today, the Warriors came at us, but we just trust in each other.

"There's a good feeling in the camp, but we do know the playoffs are coming."

Fien, who played 101 games for the Warriors said he felt no animosity towards his old club.

"What happens is a part of football, you've got to move on with it," he said.

"I was given a great opportunity to go over to the side that's running at the top of the ladder.

"I'm trying to earn my stripes and fortunately I've been lucky enough to play in two games so far, which have been two wins.

"I feel for the Warriors. I spent the pre-season with them, so I know how much hard work they've put in over the course of the year.

"They tried really hard out there today, it's one of those things, our side is on a high and is full of confidence."
