Kobbie Mainoo fans tweeted: "Manchester United were this close of getting knocked out by Coventry despite being 3 nil up in 70 min. Sack ten Hag tonight."
Sam Pilger wrote: "Erik ten Hag cannot survive this embarrassment. An implosion at 3-0 up and should have lost to a Championship side. It’s over."
One X user commented: "Fire Erik ten Hag TODAY. It’s over. It’s finished," and Ste added: "There’s never been a more stonewall excuse to sack a manager in United history before. It wasn’t this embarrassing under Moyes. Ten Hag and the squad he assembled has made a mockery of the badge."
Finally, Alex put: "Do you reckon there are people out there who think Ten Hag is a great coach and if you just get rid of all the 'bad individuals' then they'll suddenly become a really good, functional football team?"
