Sergio Aguero came off the bench to score the winner as Manchester City beat Sheffield United 1-0 at Bramall Lane on Tuesday.
Gabriel Jesus had seen his first-half penalty saved by Manchester United loanee goalkeeper Dean Henderson but Aguero replaced him to win the game for City late on.
Pep Guardiola's side are now 13 points behind league leaders Liverpool who have two games in hand while Chris Wilder's men remain in seventh place.
City were boosted with the return of defender Aymeric Laporte who started his first game for the club since suffering a knee injury in September.
