The Herald Sun reported on Wednesday that Postecoglou would quit the Socceroos even if Australia secured a place at the 2018 World Cup in Russia.

FFA released a statement on Wednesday which did not deny Postecoglouโ€™s potential departure, but said the main focus was the final games against Honduras.

The Socceroos scraped through 2-1 against Syria in extra-time in Sydney on Tuesday and Cahill said the nation should be celebrating the win.

โ€œItโ€™s just speculation, I feel that this angle, the day after the biggest game to qualify for a fourth consecutive World Cup is not needed, especially now,โ€ Cahill said at the FoxSports Melbourne Derby launch today.

โ€œI feel the angles now are before we play the biggest game and thereโ€™s an angle to try and derail us. And then Coming out of the game, thereโ€™s another angle to not celebrate a 2-1 victory. I just want us to focus on the positives.

โ€œI think we concentrate on celebrating a victory firstly and looking forward to a full house at home in Sydney in front of 80,000.

โ€œRegardless of whether people like or not, everybody is going to be watching. Speculation is always going to come with our game and itโ€™s just disappointing itโ€™s come out the day after.

โ€œ(But) itโ€™s not affecting any playersโ€ฆ Itโ€™s called professionalism.โ€

Cahill also defended Postecoglouโ€™s decision to start star Aaron Mooy on the bench against Syria.

โ€œI feel for Aaron because heโ€™s played so many games in the Premier League,โ€ he said.

โ€œWhether he starts or not I think you need to look a bit deeper into the amount games heโ€™s played. I also feel we miss the fact weโ€™re also trying to protect him, heโ€™s a professional and every single player has to sit on the bench.

โ€œEvery single player has to be part of the bigger picture to see the end result. You can say thing about many players.โ€

And for now Cahill will turn his attention to this weekendโ€™s Melbourne Derby where he looks to pull on the City blue for the first time this A-League season.

Victory lost their first game 1-0 to Sydney FC while City are coming off a 2-0 win over Brisbane Roar.

The Big V are also welcoming back Socceroos Mark Milligan and James Troisi and All White Kosta Barbarouses.

The 37-year-old said he would be ready to be a part of the starting XI or to come off the bench and is feeling great.

โ€œI feel itโ€™s important we can put on a good performance this week and we can have that derby atmosphere,โ€ he said.

โ€œOne week weโ€™re celebrating playing for Australia and next week weโ€™ll be jeering each other in a massive game.โ€

The game will be broadcasted live on FoxSports and on Network Tenโ€™s free-to-air channel โ€“ ONE.
