Alex Johnston will break the try-scoring record if he scores two tries against arch rivals the Sydney Roosters on Friday night.
The 31-year-old is currently sitting on 211 tries after scoring in round one against the Dolphins.
If he scores twice against the Roosters, he'll go past the record set by league legend Ken Irvine, who retired from the game 52 years ago.
Irvine racked up 212 tries during his illustrious career playing for North Sydney and Manly-Warringah between 1958 and 1973.
South Sydney coach Wayne Bennett says he sees similarities between the two players.
"He's a different winger, isn't he?" Bennett said of Johnston.
"If you look at Ken Irvine he's pretty much similar to him I reckon.
"They're not big guys, they don't run over the top of people, they just get there with skill and guile, great anticipation and a feel for the game.
"Some of the tries Alex has scored, you put other wingers in that position, they wouldn't score those tries because they don't have the feel that he has."
Johnston was born in Sydney, New South Wales, and has Papua New Guinean and Torres Strait heritage, descended from the Crocodile Clan of Saibai Island.
He made his debut for the Bunnies in 2014, going on to play in the grand final that year, when Souths broke its 43-year premiership drought.
Johnston is a one-club player, recording 243 NRL games so far for Souths.
Bennett says Johnston is held in high regard at the club.
"Oh very high, very high," said Bennett.
"He's a very underspoken guy here, but everyone respects him enormously.
"He's trained as hard as I've seen him train actually, and I've complimented him on his training.
"At the end of his career he could be backing off a bit with his training, but he's not, he's totally committed."
