An ex-teammate playing his milestone 250th NRL match looms as the biggest stumbling block in the Rabbitohs' push for a tenth straight victory.
Robbie Farah, who spent the first 14 weeks of the Telstra Premiership at Redfern before shifting back to Concord, is certain to provide Ivan Cleary and the Wests Tigers with some inside information ahead of Saturday's clash at ANZ Stadium.
Rabbitohs prop George Burgess knows all too well what Farah has to offer.
"He's been playing against us (in opposed training sessions) all year in training, so he knows us inside out," he said. "If anyone can take us down, it would be Robbie.
"I knew that he would be good for the Tigers going back there cause he's such a great player with a lot of experience.
"I'm happy that he's back there and doing good things – I'm sure he's going to be a great challenge for us this Saturday."
Lock Sam Burgess said the playing group enjoyed having Farah at the club, but their friendship will be on hold until after the final whistle.
"We will respect that (Farah's 250th NRL match) more after the game then before it - for us it's business," he said.
"He (Farah) was great here and we will always thank him for what he gave to the club.
"He is an absolute professional and being behind Cooky (Damien Cook) this year, for a man of Robbie's stature in the game it would been hard I can imagine.
"He was very open and up front with his decision to go back to Wests Tigers and we respected that as a leadership group and as a club.
"He wanted to finish his career playing first-grade and I think he deserves to be there judging on his performance last week."
The South Sydney enforcer added Cook will be a central figure in the Bunnies' premiership push in September.
"Cooky's been brilliant for us and for the (NSW) Blues - he brings a real dimension to the side," Burgess said.
