The former Hoops hitman, speaking exclusively to Football Insider, hailed Postecoglou
Celtic beat Raith Rovers 4-0 on Sunday (13 February) to advance in the Scottish Cup.
However, Postecoglou was left furious with his side’s performance in the first half, something McAvennie could hear over commentary.
He hailed the Hoops boss’ rants as “incredible” and wants to hear more.
“I was watching the game on TV because I couldn’t get to Celtic Park and I could hear someone shouting and bawling,” McAvennie told Football Insider correspondent Ben Wild.
“I didn’t know where it was coming from. At one point the commentator apologised and said it was Ange.
“He was effing away and all sorts at the players, he was absolutely furious with them.
“It’s because the passes were going backwards and sideways then back to the goalkeeper.
“It sounded like he was livid. I mean, for me, that’s the big talking point, that’s incredible. That’s what I want from my manager.
“If you aren’t playing well enough, you will be told about it. Make no mistake.
“This isn’t a Premiership side we are playing and we had a decent team out.
“The performance needed to be better and Postecoglou made that very clear.
“I’m so glad he did it, as I said, wow, incredible. We haven’t had that for a long time.”
