Latrell Mitchell could prove "unstoppable" at full-back for the South Sydney Rabbitohs, according to former Bunnies prop George Burgess.

Mitchell completed a move to Souths earlier this month after agreeing a departure from city rivals Sydney Roosters.

The representative star for the New South Wales Blues and Kangaroos has made it clear he hopes to feature at full-back for his new club, having operated at centre for the Roosters in recent seasons.

Asked about his ex-club's capture of Mitchell, Burgess, who has joined Super League side Wigan Warriors, made it clear he expected big things from the 22-year-old.

"I think it's a great signing," Burgess told Omnisport at the Super League season launch.

"He's already achieved so much in the game, [winning] two Grand Finals, and he's got such a massive amount of talent.

"So I think if they can get him into [the] shape of a full-back ... and get him really trim and fit he's gonna be unstoppable in that position."

With Sam Burgess now retired and brother George having moved to Wigan, Souths have also made a notable addition to their forward pack, bringing in Jai Arrow from Gold Coast Titans.

Arrow is set to link up with the Bunnies from the start of the 2021 season, although the club remain keen to fast-track his arrival if possible.

"He's an absolute machine in the forward world in the NRL, what he does in the Origin," said George Burgess of Arrow.

"I think it will be great to see him in a team like South Sydney if he can get there for 2020. He's relied on heavily in the Gold Coast team so I think to have some more high-quality players around him, it will be great to see what he can do."
