Former Manchester United captain Roy Keane was enraged after watching Manchester United fall to a 4-1 derby defeat against Manchester City.
United fell behind to Kevin De Bruyne's opener before Jadon Sancho levelled matters early on in the first half.
But Sancho's well taken equaliser was to be the last chink of hope for Ralf Rangnick's side on the day as City soon struck back, with De Bruyne easily dispatching his second goal of the game to nose City back in front before half-time.
