Jason Cundy has branded Celtic "gutless" and "spineless" as he insisted it's curtains for Neil Lennon.
The radio pundit believes the dismal 4-1 Europa League loss to Sparta Prague is unforgivable.
Celtic were routed by the under-strength Czech side and have now lost their last three home matches for the first time in 30 years.
Lennon admitted afterwards the club's knockout stage hopes are all but over but Cundy, in a scathing on-air rant, reckons their entire the season is on the brink of collapse.
"Gutless, spineless - Neil Lennon cannot survive a result and performance like that," he told talkSPORT.
"This is their worst run at home for over 30 years. They've lost three games in a row at home for the first time in 30 years.
"He was under pressure going into this, you could see he had a snap back at the press a couple of weeks about of the polls in the local media, the things said in newspapers.
"I'd like Celtic fans to tell me, now, exactly where they go from here.
"They've gone from looking for Ten In A Row, to looking at one of the worst seasons they've had in a long, long time."
