The Leeds coach made headlines in England after he held a 70-minute press conference complete with a powerpoint presentation revealing the intensive level of preparation he undertakes on each Championship opponent.
The press conference was held after a Leeds employee was discovered spying on league rivals Derby at their training ground last week.
Ahead of Australia's round of 16 Asian Cup clash with Uzbekistan in Al Ain on Monday (Tuesday AEDT), Arnold says he and his staff have been almost as thorough when it comes to researching their potential opponents in the tournament.
"That's no different to us. The only thing is I don't go to their training sessions, but that's the way modern-day football is," Arnold said.
"We know more about the opposition than we know about our own team.
"The intel is, you can't hide anything anymore these days with video. It's the type of preparation I've always done, it's about attention to detail and knowing everything the opposition is doing."
Throughout the tournament Arnold has had a team of three scouts attending various matches and providing in-depth analysis of opponents.
That includes Uzbekistan and even potential quarter-final opponents UAE or Kyrgyzstan.
"We've had scouts at every one of their games and we've had scouts at potential opponents," Arnold said.
