The Caltex Socceroos' two Premier League stars go head-to-head this weekend as Aaron Mooy's Huddersfield Town host Mat Ryan's Brighton and Hove Albion.
Vital cogs in Australia's qualification for the World Cup, the pair will become momentary rivals at John Smith's Stadium as they both aim to arrest their sides' respective form slumps.
It's expected to be a tight encounter between two teams separated on the ladder by only two points.
But which of the key Aussies will win out on Saturday night (AEDT)?
We've looked for clues with the help of Opta data.
AMONG THE ELITE
Mooy and Ryan's impressive start to life in England's top-flight has been backed up by some eye-catching statistics.
Seagulls shot-stopper Ryan ranks equal-third in the Premier League - alongside Thibaut Courtois - in terms of save percentage on shots from outside the box, keeping out 94% of attempts.
Only Manchester United's David de Gea and Burnley's Nick Pope are ahead of him.
Mooy, meanwhile, is third in the competition for number of tackles contested, with his 49 edged only by Wilfred Ndidi (59) and Idrissa Gueye (54).
It's a great boost for their respective clubs that neither player is giving the opposition an easy ride.
RYAN ON RED ALERT
With 42 saves from his 15 league games to date, Ryan canexpect another busy day at the office this weekend.
Mooy will be one of his biggest threats, having scored both of his two goals on home turf; the first in a 1-0 defeat of Newcastle and the second in the 2-1 upset win over Manchester United.
The creative midfielder is also the conductor of just about everything the Terriers do.
He's completed a whopping 209 more passes than any other Huddersfield player, and is one of only three in the squad to have featured in each Premier League fixture.
Mooy and Ryan's time in the Hyundai A-League only overlapped for a single season, but they did manage to meet four times during the 2012/13 campaign.
And it was the then Central Coast goalkeeper who ultimately came trumps as his side beat Western Sydney 2-0 in the Grand Final.
Mooy played 90 minutes but wasn't able to prevent a second defeat against the Mariners, having taken four points from the other two meetings.
Does that mean Ryan will have the psychological edge? We'll find out on Saturday night!
