The Sydney stopper is wary of the threat Phil Moss' side pose despite their recent losses to personnel as the Sky Blues add another Serbian to their ranks.They are without their skipper and have lost their two most potent attacking stars so it's fair to say A-League champions Central Coast are vulnerable right now.
But Sydney FC goalkeeper Vedran Janjetovic is warning his side not to be lulled into a false sense of security on Saturday night when the Sky Blues take on an under-strength Mariners at Allianz Stadium.
The visitors have just started life without Michael McGlinchey, who has moved to the J-League, while Marcos Flores is gone for the year due to injury and captain John Hutchinson is out suspended.
It presents Sydney with the perfect opportunity to get back to winning ways and regain their spot in the top six, but Janjetovic remains wary.
"The Mariners are a top side. They've been a top side for a long time," the in-form shot-stopper told reporters on Friday.
"Not having them two (McGlinchey and Flores) is obviously a loss for them but they've got a lot of depth in the squad, otherwise they wouldn't be doing as well as they are.
"So tomorrow we know they're going to come out nice and strong and be looking to get a few past me.
"All the boys are itching to get back into that top six. I think we deserve to be there. We haven't been playing that badly; we've actually been playing some good football.
"We just need a little bit of luck to go our way and we'll be right."
Fresh from signing a new two-year deal with the Sky Blues this week, Janjetovic believes the side is well-placed to make an assault on the finals this season.
But first they must get consistency back into their game and cut out the sloppy defensive lapses which saw them lose 1-0 to local rivals Western Sydney Wanderers last weekend.
While the Mariners may need to adjust their attacking game without Flores and McGlinchey, Janjetovic believes they still have plenty of firepower with the likes of Daniel McBreen, Matt Simon Mitchell Duke and Bernie Ibini in the squad.
"They are definitely dangermen," Janjetovic said.
"Every time we play them, we have to keep an eye on those players.
"But we'll go out and stick to our game plan and do what we've been practising through the week."
The Sky Blues will be without Brett Emerton following the former Socceroos midfielder's decision to retire this week but do have Nicky Carle (suspension) and Joel Chianese (injury) available again.
Defender Sebastian Ryall, who was an unused substitute in the derby defeat last weekend, could also return to the starting side for a clash Sydney coach Frank Farina has labelled a 'must-win'.
Asked about Emerton's decision, Janjetovic said: "Of course it's a massive loss.
"I didn't even know until it happened so I was a bit shocked. He's such an experienced player but do our best to try and fill that gap."
"Unfortunately we've lost one (Emerton) but we get two (Carle and Chianese) back.
"So hopefully that will strengthen us up front this week."
Meanwhile, Serbian midfielder Milos Dimitrijevic is likely to be part of the Sydney squad for Saturday night's clash after the club completed his signing for the remainder of the season.
The 29-year-old, who has been training with the Sky Blues for the last fortnight, joins the squad following the departure of Panamanian Yairo Yau.
"It's an honour for me to come to Australia and play for the country's biggest club," Dimitrijevic said.
"I have settled in very easily having (fellow Serbs) Nikola (Petkovic) and Ranko (Despotovic) here and it's helpful that a lot of the other players speak my language too. I want to help the club do something special this season."
