South Sydney coach John Lang is likely to resist moving Greg Inglis to five-eighth and believes the superstar recruit can "super charge" the talent in his NRL team.

Former Melbourne hero Inglis made only a cameo first appearance at Rabbitohs training on Monday, having agreed terms with the club last week for three seasons after backing out of his deal with Brisbane.

Still rehabbing after shoulder surgery, he spent just 12 minutes on the Redfern Oval ground watching his new teammates in pre-season training and chatting to Lang before departing.

With veteran centre Colin Best leaving the club, there appears to be a natural vacancy for Inglis to fill in his usual position.

But the richly-gifted back could also be on option at five-eighth ahead of John Sutton, who has shared a hot-and-cold halves combination with halfback Chris Sandow in recent seasons.

While Inglis spent some time in the halves with the Storm, Lang wasn't jumping at that possibility although he kept his options open.

"He's made his name as a centre, but he's just a great runner of the football and a very strong defensive player as well," Lang told reporters at Redfern.

"My initial feeling is he will play in the centres, but I haven't had a chance to talk to him yet about his ideas.

"He has the potential to play in other positions too."

Lang said Inglis wouldn't be doing much work initially, as he recovered from his surgery and a few "minor injuries".

However, he expected Inglis to be fit and ready to start the 2011 NRL campaign.

He believed the Test star's presence would infuse the Rabbitohs with confidence they may have been missing.

"One thing that I felt we've lacked here at Souths is a bit of real belief, when push comes to shove," Lang said.

"Having a player like Greg there, I think it's going to be a big step for the confidence of the other players.

"We've got a lot of other talent in our team, but I think he can give us a super charge."

While the Rabbitohs didn't stop training when Inglis was out on the ground, they were excited by his arrival.

"It was a great feeling seeing him come out in the Rabbitohs gear," prolific try-scoring Rabbitohs winger Nathan Merritt told AAP.

Emerging centre Beau Champion, a distant relation of Inglis, was excited at the possibility of forming a centre partnership with him.

"That would be fantastic, there's still a long time before that yet, but it's something I'm looking forward to," Champion said.
