Bruno Fernandes and Luke Shaw scored the goals as Manchester United once again enjoyed derby success at the Etihad Stadium.
Manchester City saw their 21-match winning streak come to an end as Manchester United secured a 2-0 derby victory over the runaway Premier League leaders on Sunday.
Bruno Fernandes converted a penalty after 101 seconds following a clumsy foul by Gabriel Jesus, while Luke Shaw was the unlikely scorer as the visitors doubled their lead in the 50th minute.
The result means Ole Gunnar Solskjaer has once again come out on top against Pep Guardiola, in the process becoming the first United boss to win each of his first three away trips in all competitions at the Etihad Stadium.
City may still hold an 11-point cushion at the summit but missing out on setting a new club record of 29 games unbeaten will sting, particularly considering the opposition. This is their first setback since a 2-0 reverse at Tottenham on November 21, 2020.
