The Reds have suffered a downturn in form and were poor in the 4-0 defeat to Everton at the weekend.
Pogba is making no excuses for the performance and admits the only way to repay the supporters is by showing a vast improvement against Pep Guardiola's Blues at Old Trafford.
Pogba scored twice in April 2018 as United came from two goals down to win 3-2 with an incredible second-half show at City. The Blues were poised to celebrate clinching the title but were instead forced to put the champagne on ice after a turnaround that stunned the home crowd.
