The Hyundai A-League is LIVE on Fridays 7.30pm (AEDT) on SBS ONE, SBS HD and online.

The Wanderers goalkeeper described Gameiro's comments as "simple", lighting the fuse for an explosive showdown at Allianz Stadium on Saturday night.

In an otherwise dour pre-match press conference Covic bristled when reminded of 21 year-old Gameiro's barb.

The Wanderers have made the past two A-League grand finals, have qualified for the 2014 AFC Champions League final, and feel they deserve to be on equal footing with Sydney FC.

"Oh yeah," Covic said. "It's funny how the youth can throw out simple comments like that, isn't it?

"Little brothers, yeah.

"Well okay. Well, good on him."

The Wanderers went through their paces at Blacktown on Friday, with captain Nikolai Topor-Stanley looking a likely starter after completing the session.

After the side leaked a club-record four goals in the Round 1 loss to Melbourne Victory, the Wanderers are hoping Topor-Stanley's presence in defence can help turn things around.

The Australia defender's fitness will be tested, given he's only just arrived home from playing 90 minutes for the Socceroos in Qatar, and he'll have a big job to do on Sydney FC marquee Marc Janko.

Tomi Juric is also back in the Wanderers side after suffering a groin injury on the Socceroos training camp.

Coach Tony Popovic said Austrian international Janko, who stands at nearly two metres tall, would not alter his side's strategy.

"He's a proven goal scorer. He's a player we'll have to look out for tomorrow," Popovic said.

"We don't do anything specific in regards to (his height). We prepare for every situation and we're well aware of his strengths.

"You have to be aware of it but you don't have to fear it either. We've got our on strengths we want to play to."

After twice breaching the 40,000 attendance mark last season, the first Sydney Derby of the 2014-2015 season has sold out.

Sydney FC CEO Tony Pignata is delighted by the prospect of a full Allainz Stadium.

"I’m extremely pleased we’ve been able to put the sold out signs up today," he said.

"It just goes to show the impact Sydney FC has on football in this country that we can welcome 40,000 crowds for games at our home ground and I'm looking forward to what should be a great spectacle on Saturday night.

"Nothing is better than seeing Allianz Stadium bathed in Sky Blue and I’m sure that with the full support of the Members and fans behind the players, they can put on a performance to be proud of."
