Gold Coast enforcer Anthony Laffranchi admits the high-flying Titans are wary of a South Sydney side fighting desperately to stay in the race to the NRL finals.

Souths have had their necks on the top-eight chopping block for weeks.

But with their season on the line last Saturday, coach Jason Taylor's Bunnies had their tails up as they managed to pull off the unthinkable.

The Bunnies dug deep to overturn a 12-point deficit against defending premiers Manly and went on to score their biggest victory at Brookvale since 1954 to remain in finals contention.

It's that fighting spirit which has caught the Titans' attention and Laffranchi says no one should underestimate a desperate side fighting for survival.

"Souths are dangerous across the park and manage to score points," Laffranchi told reporters on Thursday.

"But as they showed last week, they were able to stop points as well.

"They're desperate. It goes to show last week against Manly, 12 points down and claw their way back to win the game.

"They're playing like a desperate team, defending desperately and putting out some good wins."

The Titans are firmly entrenched in the top eight and a win on Friday against the Rabbitohs at ANZ Stadium would go a long way to sewing up a top-two finish and snaring the all-important double chance.

Next up, they'll return to Skilled Park to host strugglers Cronulla and an unpredictable West Tigers outfit before playing their last-round match against Manly at Brookvale.

But Laffranchi says the Titans aren't getting ahead of themselves.

"We're in that (finals) position now and I suppose each week you just want to win," he said.

"I suppose whilst we're doing that we can lock that top two away."

The Rabbitohs have lost Roy Asotasi for the season through injury and will have to dig deep to cover the workload of their sidelined captain.

The Titans have yet to post a win at ANZ Stadium and the Bunnies will be hoping the home ground advantage will benefit them.

Former Rabbitoh Mark Minichiello says the Titans have drawn a lot of confidence from their massive victory over the Warriors in New Zealand last week.

"We did a lot of work on our defence the last couple of weeks and it really paid off for us," Minichiello said.

"Our defensive effort against the Warriors is probably the best we've had all year.

"So if we can take that into the game against the Bunnies, I'm sure our attack will fall into place and the points will come.

"Our momentum is starting to build from here on in, we get a win this week, then two home games coming up I think. We'll have a really good run coming into the semis.

"There's a lot of confidence within the group so we're pretty confident that we can get the job done."
