Former Manchester United star David Beckham described Sunday's 2-1 derby victory over Manchester City as a 'big win'.
United, managed in a derby by new boss Ruben Amorim for the first time, were losing until the 88th minute courtesy of a first-half strike from Josko Gvardiol.
But Bruno Fernandes equalised from a penalty before Amad Diallo - who had won the spot-kick - netted a late winner.
Despite Sunday's impressive result, United remain in the bottom half of the Premier League table after making a poor start to the season, largely under former boss Erik ten Hag.
