Kevin De Bruyne and Riyad Mahrez both scored twice as Manchester City condemned their rivals to a humiliating 4-1 loss.
“For a player in a derby, or any game, to give up, it’s unforgivable really.
“The beauty of top-level sport is there is no hiding place. We saw all United’s shortcomings today.
“There’s ways to lose football matches, we’ve all lost football matches, but the way United lost today. They stopped running. They gave up. There’s players out there not running back.
“That’s what I don’t understand. The manager will be criticised, and the tactics, but players not running back when they are playing for Man United is unacceptable.
“They threw the towel in, which is shameful.
“I forgive mistakes, but you’ve got to run back. There’s five or six players who should never play for Manchester United.
“It’s shameful. A couple of lads in midfield, (Aaron) Wan-Bissaka, Fred, (Marcus) Rashford came on. I could go on. And City weren’t even at their best. They didn’t have to be.
“They gave up, Shame on them!”

At the top of the table, Liverpool also have a game in hand to reduce Manchester City’s advantage to three points.
