A four-time Kangaroos and Blues representative, centre Mitchell has signed for 2020 and the Rabbitohs hold an option to extend his deal for a further year.

"He has the ability to be one of the best players in the world and from our discussions with him he understands that it's going to take a lot of hard work and effort for him to be at his best consistently and to reach his full potential," Rabbitohs general manager of football Shane Richardson said in a statement.

"He will get that opportunity at the Rabbitohs, working with some wonderful mentors here in Wayne [Bennett], Jason [Demetriou], Ben [Hornby], Greg [Inglis], John [Sutton] and Sam [Burgess], and we're really looking forward to seeing Latrell at his peak wearing the famous cardinal and myrtle jersey that so many greats of the game have worn before him.

"He understands 'The Rabbitoh Way' and what it means to represent the Rabbitohs. He has a family connection to our club with his father Matt having played here, his family are South Sydney supporters, and we're looking forward to welcoming him and his young family to the Rabbitohs this year.

"He is a very proud Indigenous man, a young leader in the Indigenous community and we know that he will be of great support to Souths Cares and its programs in the Indigenous community.

"Things in the player market changed recently which saw us move into a position to be able to bring him to our club, and for him to make us his club of choice.

"We're very excited that this opportunity has come to fruition and our members should be equally as enthusiastic about having a player of Latrell's ability joining our ranks."

Mitchell helped the Roosters win the NRL premiership in 2018 and 2019, while the Rabbitohs fell in the Preliminary Finals last year.
