Darren O’Dea saw Ange Postecoglou up close. As Celtic’s B team manager at the time, he worked alongside him and watched how he set standards across the club.
From the outside, Postecoglou’s impact was clear in the way Celtic played. Fast, direct, brave on the ball. But inside Lennoxtown, the detail ran deeper than patterns and pressing triggers.
O’Dea has lifted the lid on how Postecoglou kept control of everything without saying much. It was not about shouting or constant reminders. It was about presence and quiet authority.
The story centres on something as simple as GPS data from training. Numbers, reports, distance covered. The kind of information that floods inboxes every day at a modern club.
He said: (Open Goal), “He was in Celtic for three months and you know the pods that you train with GPS and the reports come in, what, an hour after training at Celtics.
“26 players and there’s loads of numbers on Everton, distance covered. You need the microscope to go through every one of these. There’s no chance you go through everyone.
“Ange hadn’t replied to one email that these got sent in, in three months. And one day one player’s pod wasn’t working and within five minutes Ange was back saying, where’s the player’s pod?
“And the sports science staff sh** themselves then because they realised this guy is watching everything. But he’s not feeding back anything. And then he just had everyone on edge all the time.”
As fans, you could see that edge straight away. Celtic trained the way they played. Quick. Brave. Aggressive with the ball. The patterns weren’t slow walk-throughs, they were done at real speed. Full-backs stepping inside without fear, wingers pinning their man back, midfielders demanding it on the half-turn. It all looked sharp because it had to be.
When they swarmed teams late on and kept the tempo high into stoppage time, that wasn’t luck. It was repetition. It was standards set on a Tuesday morning when nobody was watching from the stands.
The GPS story sums it up. Ange didn’t need to shout about the data or fire off replies to every report. He just needed people to know he was checking. The second a pod went missing, he clocked it. That tells you everything.
As supporters, that’s what you want from a manager. The feeling that nothing slips. Under him, it felt like Celtic were run properly again. Everyone knew the level. And everyone knew there was no hiding from it.
