Thunder and lightning heading Rabbitohs' way

South Sydney aren't too concerned with what the future might bring in terms of chatter about James Roberts or Latrell Mitchell because they've got giant Cowboy Jason Taumalolo knocking on their door this weekend.

Senior players Sam Burgess and John Sutton danced delicately around the questions of whether they wanted - or even needed - Roberts and Mitchell as new additions to the club.

Mitchell has 18 months left on his Roosters contract and Roberts has until the end of 2021.

But reports have been circulating that the Broncos centre isn't happy under the new Anthony Seibold regime, while Souths are contemplating filling the Greg Inglis vacancy.

"I've not given it much thought. Until it's news I don't really buy into it," Burgess said when asked about the Roosters centre, who amassed 26 points against the Wests Tigers last weekend with a hat-trick and seven goals.

"He's a cracking player I know that. But if anything happens, it happens, otherwise I'm not turning my head to it."

It's the same deal with Roberts as far as Burgess is concerned.

"There's talk about a lot of things. I don't buy into it because the game moves quick; things happen quick; and things change quickly too," he said.

"I don't get too excited about stuff, so you don't get too disappointed either. We're doing alright at the moment.

"If someone comes, that's great, but if not it's not too a big a deal because we're doing quite well with what we've got."

Sutton referred to South Sydney's depth with backs Adam Doueihi (knee) and Braidon Burns (ankle) out injured but replacements, like back-rower Kyle Turner, stepping into left centre with aplomb.

"Latrell Mitchell is one of the stars of the game. But I heard him say he's never even talked to Souths so I don't know what the deal is there," Sutton said.

"All clubs want to get those sorts of players to their clubs, and we're probably no different.

"But the depth here is really good. The way the boys have been going and I think of Kyle. He never trained at centre in the pre-season and he's out there doing a great job.

"It's the same sort of thing [with Roberts]. I've been in the game a long time and you hear this sort of stuff all the time.

"I'll just worry about what I'm doing. It could be my last year here, who knows. I'm concentrating on what I need to do to get my body right so I can perform on the weekends."

And this Sunday presents another hurdle in Taumalolo, whose return from a knee injury last week brought the Cowboys instant results - their third win of the season.

At Suncorp Stadium, the Queensland faithful are certain to be cheering every time Taumalolo makes a run at a Souths forward like his opposite No.13 Cameron Murray.

"We all can see what Taumalolo can bring to the team – saw that on his return last week for the Cowboys when he ran for 200 metres quite effortlessly," Burgess said.

"That's what he does. He carries the ball a lot so we've got to try and not let him cause too much damage in those runs.

"Cameron is competent and sets high standards for himself, so do the others in the middle. We have a job to do. We've played him before so I'm sure we'll be alright."
