Having been in mixed form for club and country, Risdon looks set to relish the attacking freedom he'll have under Arnold.
"As a fullback [Arnold] wants us to get really high and getting those runs and balls into the box," Risdon said.
"That's really enjoyable, the way I want to play. I like going forward a lot. It's a lot of work but I really enjoy it."
Rested against Lebanon, Risdon seemingly did enough to convince Arnold he will be the man to start at right-back in January.
Loser: Robbie Kruse
He deserves far more credit than he gets for most of his performances in the green and gold, but Kruse faces a fresh challenge to keep his starting spot.
While excellent at reading a game and providing defensive cover, Kruse's shortcomings in attack were on full display against Korea Republic.
A shot that went out for a throw-in indicative of an attacker who has scored just five goals across 69 Socceroos appearances.
Rested against Lebanon, new wingers Martin Boyle and Awer Mabil pushed their cases for a start with the former particularly impressing.
Craig Goodwin is also knocking on the door for Kruse's spot with his left foot a potential handy asset for Arnold.
With Mathew Leckie nearly unmovable on the right flank, that leaves four players fighting for one spot and Kruse looks like he'll struggle to walk away a winner leading into the Asian Cup.
Winner: Graham Arnold
While both scorelines could have been better, the new Socceroos coach has very quickly left a positive mark upon this Australian side.
Though far from the finished product, the green and gold have quickly embraced Arnold's attacking emphasis.
From constant pressing without the ball, to his now trademark use of full-backs, Arnold has wasted no time leaving his mark on the Socceroos and he'll be bouyed to see how quickly he's rubbed off on them.
His encouragement from the sidelines has been hard to miss too as he looks to organise his side and give them the confidence to play a new brand of football.
While Arnold's true first test will come at the Asian Cup, the early signs have been promising.
With the strikers struggling to get involved on the ball, the Socceroos had real trouble with accuracy in front of goal against Korea Republic and Lebanon.
Despite dominating play on Saturday, only nine of Australia's 22 shots were on target as they had to wait until injury-time to equalise in scrappy fashion.
It was a similar story against Lebanon with only seven of the Socceroos 21 shots landing on target.
Arnold has backed a number of players to step up and score goals in Tim Cahill's absence, but it's clear most still need to find their range in front of goal.
Tom Rogic was arguably too ambitious with his shooting against Korea Republic - something a number of Socceroos were guilty of across the two games.
For a side that has struggled for goals, Arnold might be encouraged to see his side at least having a crack but it will take time for them to fire with accuracy.
