Cundy described the loss as an “absolute disaster”.
United took the lead through Cristiano Ronaldo, but they conceded twice after Aaron Wan-Bissaka’s red card.
Antonio Conte is available after leaving Inter Milan at the end of last season and the Italian could provide the type of short-term success that United so badly need.
Cundy told talkSPORT: “United got exactly what they deserved and he’s been exposed again brutally
“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.”
