Ally McCoist joked he's "going right off football" after his beloved Rangers were battered by Celtic.
The Ibrox legend was back on punditry duty on Thursday morning as he fronted up to Celtic-supporting pal Alan Brazil on talkSPORT.
McCoist was in the Parkhead stand to see his team take a drubbing in Glasgow's east end but he offered no excuses for a dismal derby display.
Ange Postecoglou's side ran out 3-0 winners to replace their rivals at the top of the Premiership table, much to Brazil 's delight.
He was discussing Sunderland being linked with Roy Keane before admitting he felt McCoist could've been a potential candidate for the the Black Cats.
But McCoist said: "Not for me Al. I'll be honest with you mate, I don't know what it is, I've just gone right off football mate, I've lost my appetite for it..."
Brazil replied: "What? After last night?"
And a laughing McCoist admitted: "Correct!"
Perhaps surprisingly, Brazil refused to stick the boot in despite a first derby win for his team since 2019.
He said: "People know the score and I'm not going to rub it in, because there's still a long way to go, right?
"So, two points: one was Celtic just pressed the living daylights out of Rangers. Urgency, ball boys were throwing the balls on, getting on with it and Rangers couldn't cope.
"(Allan) McGregor again, it could've been five or six at half-time had it not been for McGregor."
McCoist couldn't help but agree, insisting Celtic were outstanding in a blistering first-half blitz that yielded all three goals.
He said: "100 per cent. I thought Celtic were excellent first-half, by the way. I did expect them to come out the traps and have a go but I just thought Rangers could not handle or match their intensity.
"I know Hatate scored a couple of goals and played well, but I thought (Josip) Juranovic was outstanding, and Jota."
