United were beaten 2-1 by Swiss minnows Young Boys in their Group F opener on Tuesday night – a result which has left many of Solskjaer’s decisions in the spotlight.
The Norwegian opted to take off midfielder Donny van de Beek for centre-back Raphael Varane at half-time to bolster the defence after right-back Aaron Wan-Bissaka’s red card.
But Cundy claimed that left the Red Devils “overrun in the middle of the park” as he launched a withering attack on Solskjaer.
“That there shows he’s utterly clueless,” Cundy told talkSPORT of the result in Bern. “That performance, the team shape… they went down to 10 men, yes, but come on.
“They went to five at the back and he didn’t change it. They were getting overrun in the middle of the park.
“Poor Fred, Paul Pogba and Bruno Fernandes. I’ve got so much sympathy for them, they had no help, they were getting passed around.
“The back five didn’t move, they were getting outnumbered. It wasn’t working, they should have gone for four in defence and four in midfield.
“United got exactly what they deserved and he’s (Solskjaer’s) been exposed again brutally.
“The game changed on the red card but that didn’t mean it was over.
“Young Boys are normally whipping boys of European football and United get rolled over 2-1… it was a disasterclass, it was an absolute disaster.”
Cundy did not stop there and declared the defeat was tantamount to a sackable offence as he highlighted former Chelsea and Inter Milan boss Conte as the ideal replacement for Solskjaer.
He added: “It exposed Ole, it did badly. I’d sack him. We know what’s coming, don’t we? You’ve got Antonio Conte out there…
“Who’s the better manager? There will be a stage in the season where they’ll be like ‘I wish we did it earlier.’
