Many of Australia's overseas brigade have a spring in their step after Bert van Marwijk's naming of a preliminary 29-man squad for the Caltex Socceroos' upcoming friendlies.
But with that list still to be trimmed, now is the time to produce on the pitch.
Check in with where the national team hopefuls are headed this weekend.
ROGIC TARGETS MORE OLD FIRM MAGIC
Tom Rogic steps back into the cauldron this Sunday (11:00pm AEDT) as Scottish Premiership leaders Celtic head to Rangers in the Old Firm derby.
Though the Hoops have a game in hand, the title race is not yet over with Rangers in a position to cut the gap back to three points.
Rogic netted the opener in his side's 2-0 win at Ibrox in September and started in last weekend's Scottish Cup victory over Greenock Morton.
The match will be broadcast live in Australia on beIN Sports.
The midfielder isn't the only Aussie set for a white-hot derby atmosphere in Scotland as Jamie Maclaren's Hibernian host Hearts (Saturday 6:45am).
Maclaren's men are currently nine points ahead of their Edinburgh rivals.
RYAN ROLLS ON TO MERSEYSIDE
Mat Ryan's Brighton and Hove Albion are full of confidence following their massive win over Arsenal and will be looking for more of the same at an out-of-form Everton (Sunday 2:00am).
The teams drew 1-1 at the Amex Stadium in October.
Elsewhere in the Premier League, Aaron Mooy is expected to be fit for Huddersfield Town's visit from Swansea City (Sunday 2:00am).
Mooy has missed the Terriers' last three matches following a gashed knee.
JEDINAK'S TOP-OF-THE-TABLE TEST
Aston Villa, currently four points off the Championship's top two, face a stern examination when leaders Wolves arrive at Villa Park (Sunday 4:30am).
Jedinak played 30 minutes in the midweek win at Sunderland and could be called into the starting XI to keep a lid on the division's joint-top scorers.
At the other end of the table, Jackson Irvine will be hoping to help Hull City steer clear of danger in what is a winnable home game against Norwich City (Sunday 2:00am).
Hull are coming off the back of a midweek defeat to Tim Cahill and James Meredith's Millwall, who will expect to keep their form going against Brentford (Sunday 2:00am).
Elsewhere, Bristol City's personnel problems mean Robins skipper Bailey Wright could play in his preferred centre-back position at Burton (Sunday 2:00am), while Massimo Luongo will be confident for Queens Park Rangers' clash with Sunderland (Sunday 2:00am) following his late equaliser last time out.
REST OF EUROPE
Mathew Leckie will be hoping to help Hertha Berlin out of a form slump as they entertain fellow mid-table Bundesliga mid-table Freiburg (Sunday 1:30am).
Robbie Kruse is also back in action in Germany's second tier, with VFL Bochum welcoming Kiel on Saturday (11:00pm AEDT).
Elsewhere on the continent, Danny Vukovic's Genk warm up for next week's Belgian Cup final with a visit from fourth-placed Gent (Monday 12:30am).
And it's a big game for Tomi Juric in Switzerland - his Luzern host powerhouse Basel (Monday 2:00am).
Over in Turkey, Aziz Behich's Bursaspor will look for back-to-back victories in a trip to cellar-dwellars Osmanlispor on Saturday (Sunday 12:00am).
Nikita Rukavytsya is looking to add to his seven league goals in Israel as Maccabi Haifa head to second-bottom Hapoel Ashkelon (Sunday 4:00am).
Meanwhile, Czech outfit Mlada Boleslav and their Caltex Socceroos preliminary squad member Aleksandar Susnjar continue their battle against relegation away to 12th-placed Brno (Monday 1:00am).
In the UAE, Mark Milligan and Al-Ahli host Al-Wasl in the UAE League Cup (Monday 3:15am).
And in Japan top-of-the-table Nagoya Grampus are back on the road to Shonan Bellmare (Sunday 6:00am), where Mitch Langerak will be hoping for a second straight J.League clean sheet.
