Adelaide United defender Nigel Boogard is wary of his former A-League club, Central Coast.
While many pundits question whether the Mariners are on the wane, Boogard isn't among them.
"They have obviously got great depth in their squad to still be able to be in the position they are with not great results in the past month and a half," Boogard said.
The Mariners have won just five of 11 games since the start of the New Year yet remain in second spot on the ladder, five points behind Western Sydney.
And Boogard, who played 55 games for the Mariners before joining Adelaide, said there was no chance the Reds would treat them lightly in Sunday's clash at Hindmarsh Stadium.
"They are well balanced defensively. They are very well organised and hard to break down," Boogard said.
"Going forward, they have got some boys who can really push you on the counter-attack with some pace out wide.
"And they have got guys up front who know how to find the back of the net."
Boogard's respect for the Mariners is well-placed, given Adelaide haven't beaten Central Coast since September 2009.
But Booagard said Adelaide should worry more about themselves than the seven-game losing streak against Central Coast.
"For us, it's about doing what we need to do well to get the result," he said.
"It's just a matter of us concentrating on what we need to do when we have possession, keeping it and waiting for the right time to attack.
"We also need to be solid defensively because when we defend well we usually get a result."
Both clubs will be without their first-choice goalkeepers, with Adelaide captain Eugene Galekovic and the Mariners' Matt Ryan on Socceroos duty.
The Reds are set to welcome back striker Bruce Djite from a groin injury but have lost playmaker Marcelo Carrusca (groin).
