Roy Keane was left in a state of shock after Manchester City raced into a 4-0 lead over Manchester United before half time.
United started nervously and City pounced with Phil Foden blasting them ahead within ten minutes. Two goals for Erling Haaland and another for Foden have since followed.
With United fans leaving before the break, barring a miracle, the game is as good as over. Speaking on Sky Sports at half time in the Derby, former United captain Keane struggled to put into words how poor United had been.
