Australian teammates Tim Cahill and Mark Schwarzer will become enemies in the English Premier League this weekend.
On Sunday, Fulham host Everton at Craven Cottage as Schwarzer will be hoping Cahill isn't at his deadly best as both sides strive to pull themselves out of the bottom six.
Also in the EPL, Socceroos duo Vince Grella and Brett Emerton will be at home with Blackburn as newcomer Wolves comes to Ewood Park.
Whilst Grella is expected to play more minutes in the first team, Emerton could start after a long layoff with a knee injury.
Blackburn are looking for their first win of the season.
In Scotland, Scott McDonald and Celtic are at home to Dundee United whilst Danny Invincibile and Kilmarnock take on Hearts at Tynecastle.
In the English Championship, Nicky Carle's Crystal Palace are at home to Scunthorpe United whilst Middlesbrough may welcome back goalkeeper Brad Jones after an ankle injury has kept him out recently.
Jones is expected to join fellow Aussie Rhys Williams in the Boro starting line-up as they host Ipswich Town and Adam Federici will figure in goals for Reading who are expecting a visit from Doncaster Rovers.
