Seibold: We should have gone on with it

South Sydney Rabbitohs coach Anthony Seibold has praised the most dominant attacking performance from his side this year but expressed frustration at letting in two late tries – and four overall – in what could have been an even more dominant result.

The 42-22 win over Canberra at Central Coast Stadium still had plenty of positives, though Seibold refused to speculate on what could be another suspension for star lock Sam Burgess for his high shot on Aidan Sezer.

"It was probably our most complete attacking performance," Seibold said.

"I thought we did a really good job with our shape, but defensively I wasn't comfortable with leaking four tries, particularly those two at the back end of the game, I thought we need to be a bit more ruthless."

He said he was "disappointed we didn't go on with the job".

"One of the challenges when you get out to 42-12, you want to be ruthless. We had an opportunity to be ruthless and put the foot on the throat and I don't think we did that. The team agrees,'' Siebold said.

"We spoke about what we did well in the game and what we need to improve. You don't get yourself in those situations too often when you're out by that lead because the competition is so tough...so when you do get an opportunity, we need to be better at the back end of the game."

Burgess was exceptional through the middle of the big Canberra pack with 203 metres, six busts, four offloads and a line break before being substituted shortly after his 59th-minute hit on Sezer saw him placed on report.

"I'm not going to make any comment about that. But he was brilliant. I'm not sure about fired up, but he probably saw two pretty gritty performances from us [while he was suspended] and him being a competitor he probably wanted to get back out there. He was ready to play," Seibold added.

Skipper Greg Inglis laughed his own 80-metre intercept try but praised strong efforts from all three Burgess siblings through the middle.

"[Sam] is one of our leaders and it's great to see him back. I thought his other two brothers (Tom and George) did really well,'' he said.

"The (Burgess) twins have been exceptional for us. I think I speak for all the backs when I say we're lucky enough to play off the back of them."
