Sydney FC are still looking to properly "put a team to the sword" and midfielder Brandon O'Neill senses the time is right against Western Sydney Wanderers on Saturday.

With the season's second Sydney derby looming, each side of the cross-city chasm is recalling how the first played out in October.

Earlier in the week Western Sydney playmaker Roly Bonevacia was quick to call the Sky Blues lucky for pulling off a 2-2 draw at Allianz Stadium, citing a penalty just before halftime as the moment that swung the contest in their favour.

Arnold hails leaders Sydney FC's strength of mind
Sydney FC coach Graham Arnold says removing self-doubt from his players is a key to his A-League club's stunning success.

O'Neill's view is stark in its difference, and the 23-year-old issued a menacing caution the Wanderers could be set for a return to their long-time derby drought prior to February's Western Sydney breakthrough.

"All I see (in that game) is a sign of a champion team," O'Neill said.

"When the sticks are down in the first half and we concede two goals back to back, we re-group at half-time.

Sydney FC's O’Neill being chased by Ireland
Sydney FC star Brandon O’Neill has long been touted as a future Socceroo, but the midfielder might soon be faced with a choice about his international future.

"I think any other team could have thrown in the towel and said it's not our night, but that's not what we're about at Sydney FC. That's not our team culture.

"We came out in that second half and personally I think we could have won it with the chances we had at the end."

In line with Sydney's party policy of not talking about the opposition, O'Neill stopped short of declaring the injury-racked Wanderers are there for the taking at ANZ Stadium.

Popovic roots hinder Gombau's philosophy, reveals Baccus
Western Sydney midfielder Kearyn Baccus predicts new coach Josep Gombau may offload defenders in January and replace them with pace further up the field.

Instead, he echoed coach Graham Arnold's mantra that the team, now five points clear at the summit, are still far from their best.

"You look at it in depth and you know you can improve but we're still winning football matches," he said.

"Which is the scary thing because on a weekend when we put everything together, we could really do damage and put a team to the sword.

"What better way to do that than this Saturday?"
