Aziz Behich
Move: PSV Eindhoven to Istanbul Basaksehir
Behich signed a three-year deal with the team from the Turkey's heartland in May after failing to break into Mark van Bommel’s PSV side last season.
It’s a second stint in the Turkish Super Lig for the Caltex Socceroos left-back after a six-season spell at Bursaspor from 2012-2018 in which he featured over 100 times.
Behich, who made just six appearances for PSV last season, will be competing with former Arsenal and Manchester City star Gael Clichy at left-back and joins a squad which includes the likes of ex-Barcelona man Arda Turan, Brazil forward Robinho and ex-Premier League marksman Demba Ba.

Milos Degenek
Move: Al-Hilal to Red Star Belgrade
Degenek had only left Red Star, the defender's childhood club, in January this year to join Al-Hilal but made the switch from Saudi Arabia back to Serbia in July.
He enjoyed an excellent time in his first spell with Red Star, playing in the UEFA Champions League where his side managed a famous win over eventual winners Liverpool last November.
The 25-year-old has already helped the Serbian champions move closer to entering this season's top tier European tournament, having dispatched a penalty in the club's epic penalty shootout win over Copenhagen on Wednesday morning's third round qualifier.
Next up for Degenek? A two-legged play-off tie with Switzerland giants, Young Boys.

Alex Gersbach
Move: Rosenborg to AGF Aarhus
The classy left-back linked up with fellow Caltex Socceroo Mustafa Amini in July when he signed with Danish outfit AGF from Norwegian giants Rosenborg.
Gersbach, who spent last season with Norwegian club Rosenborg and relegated Eredivisie outfit NAC Breda, inked a three-year deal with the Danish Superliga club.
As well as Gersbach and Amini, AGF also have ex-Brisbane Roar attacker and young Australian starlet Zach Duncan on their books.

Craig Goodwin
Move: Adelaide United to Al-Wehda
After a sensational season in the Hyundai A-League with the Reds, Goodwin was snapped up by Saudi Pro League outfit Al-Wehda on an undisclosed fee in July.
Goodwin enjoyed a standout season for the Reds in 2018/19, highlighted by his match-winning brace in the 2018 FFA Cup Final and his tally of 10 goals and nine assists in 29 league appearances.
As well as that move abroad, Goodwin also earned a Caltex Socceroos recall, playing in June's friendly against the Korea Republic in Busan.

Robbie Kruse
Move: VfL Bochum to Melbourne Victory
After eight seasons playing abroad, the Caltex Socceroos winger is back in the Hyundai A-League having signed a two-year deal with Victory in July.
The 30-year-old was let go by 2. Bundesliga side Bochum in June and jumped at the chance to return to Australia.
Kruse, who has featured 75 times for the Caltex Socceroos, made his name at Victory a decade ago and is back as one of the key recruits of new coach Marco Kurz, appointed the club's boss following the departure of Kevin Muscat.

Massimo Luongo
Move: Queens Park Rangers to Sheffield Wednesday
All-action midfielder Massimo Luongo made a deadline day switch from Championship club QPR to Sheffield Wednesday.
A 42-times-capped Caltex Socceroo, Luongo became Wednesday’s fifth acquisition of the transfer window after agreeing to a three-year deal with the Owls.
In four years with QPR, the 26-year-old racked up nearly 150 appearances and scored 10 goals.

Mark Milligan
Move: Hibernian to Southend United
After leaving Scottish Premier League outfit Hibernian, the Caltex Socceroos skipper found a new home at League One club Southend United in July.
Milligan, 34, inked a one-year deal at Roots Hall and was quickly appointed as club captain.
There is also an additional option for a further year on Milligan's contract, although the deal also includes at least a further two years in a coaching role with the academy or first team.

Aaron Mooy
Move: Huddersfield Town to Brighton and Hove Albion
Just when it appeared Mathew Ryan would be the only Caltex Socceroo in the Premier League this season, Brighton and Hove Albion secured the services of Mooy on loan.
The 28-year-old linked up with Aussie 'keeper Ryan in East Sussex on deadline day after a late swoop from the Seagulls for the Huddersfield Town midfielder.
Mooy played 65 games in the Premier League over the last two seasons for the Terriers, tallying seven goals and four assists.

Andrew Nabbout
Move: Urawa Red Diamonds to Melbourne Victory
Nabbout called an end to his 16-month stint on the books of J-League club Urawa and re-joined his hometown club Victory in late July.
The 26-year-old attacker was a product of Victory’s youth system and made his professional debut for the Navy Blues in 2012.
And Nabbout made a scintillating start to life back in Victoria, scoring a brace in their FFA Cup 2019 Round of 32 clash with former club Newcastle Jets.

Harry Souttar
Move: Stoke City to Fleetwood Town
The giant central defender earned a move back to League One outfit Fleetwood from his parent club Stoke on loan for a second time, having joined Joey Barton's side in the January transfer window last season.
And it took just four minutes into the new season for the move to pay dividends, with Souttar scoring a trademark header in their opening day 3-1 win over Peterborough.
While Souttar is yet to win a senior Caltex Socceroos cap, he is very much in Graham Arnold's sights after being involved in June's camp in Korea Republic.
The 20-year-old is an Australian youth international and played for the U-23 squad in March's AFC U-23 Championship.
