Complacency and cross-town rivals Greater Western Sydney are all that stand between Sydney and their best start to an AFL season in nine years.
The Swans haven't enjoyed a 5-0 start since 2012, when coach John Longmire helped deliver a premiership in his second year in charge.
Sydney, one of three undefeated sides after the opening four rounds in 2021, host the Giants at the SCG on Saturday.
"The most dangerous thing for us is to be complacent. It's good that we're not, we're still hungry to keep going," Swans midfielder Oliver Florent said.
"We know they (GWS) are a very hungry team ... we've always had a great rivalry.
"To win against Collingwood isn't an easy task ... they've lost a few of their good players, but they've got players who can easily fill roles."
This weekend will mark the 20th meeting between Sydney's two sides.
The Swans have won 12 derbies, including last year's upset at Optus Stadium that was arguably the lowest point of the Giants' 2020 struggles.
"We didn't have the greatest year and to get a win over them, a quality side, was good," Florent said.
"It was a long time ago, we've got a lot better since then.
"I've had full confidence in this group ... there's really no surprises to me (about the Swans' form)."
Curbing the influence of GWS stand-in skipper Toby Greene shapes as one of the Swans' biggest worries this weekend.
Greene is coming off a pair of five-goal hauls, while he booted three goals during a pre-season win over the Swans.
George Hewett, who is among numerous Swans to enjoy an eye-catching start this season, is an obvious candidate for the tough job.
"I trust Georgie with my life," Florent said.
"There could be a few of them who could have the job ... most of the defenders will be putting their hands up."
The Swans have a nine-day break between their win over Essendon and their clash with GWS, which should help Lance Franklin back up and play consecutive games for the first time since 2019.
But Dane Rampe and Isaac Heeney won't be available due to hand injuries.
Defender Rampe underwent surgery on Monday to repair a broken finger sustained during training two weeks ago.
"We were hopeful Dane may have been able to avoid surgery but a decision to operate was made this morning after further consultation with the surgeon ... At this stage, we expect Dane will miss the next three to four weeks," general manager of football Charlie Gardiner said.
Forward Heeney will miss two or three weeks after suffering a broken hand early in the victory over the Bombers.
"It sucks he (Heeney) can't be out there," Florent added.
"He's going alright. It's a tough thing, breaking your hand."
