Erling Haaland struck from the penalty spot after 26 minutes and then headed home shortly after the interval before Phil Foden put an emphatic stamp on a 3-0 victory for Pep Guardiola's visitors.

While City laid down a marker in their Premier League title defence, United's defeat was their fifth in just 10 matches this season and left them 11 points adrift of leaders Tottenham.

Assessing what United can do immediately in an attempt to rectify their failings amid a turbulent time for the club both on and off the field, former skipper Keane suggested taking the armband off Fernandes, who assumed the role from out-of-favour defender Harry Maguire ahead of the campaign.

Keane, who captained United from 1997 to 2005 during one of the club's most successful periods, told Sky Sports: "After today, having watched him again, I would definitely take the captaincy off him.

"One hundred per cent. I know it's a big decision, they've changed the captaincy with Maguire. But Fernandes is not captaincy material.

"I think he's talented player, no doubt about it, but what I saw today¦his whinging, his moaning, his throwing his arms up in the air constantly, it really isn't acceptable.

"What we saw today, I would take that off him. The manager is capable of doing that. He's the opposite to what I would want in a captain."
