Juan Mata scored the only goal of the game as Manchester United overcame bitter rivals Manchester City 1-0 in the EFL Cup fourth round on Wednesday.
The result enabled Jose Mourinho to exact some revenge over old foe Pep Guardiola at Old Trafford, following City's Premier League win back in September.
A lacklustre first half saw the teams go in goalless at the break, but Mata was on hand to finish Zlatan Ibrahimovic's cross in the second half, sending United through to the quarter-finals of the League Cup.
Here, Sportsmail's CHRIS WHEELER and MATT MALTBY rates the players at Old Trafford.
