City's defeat at Crystal Palace left Manuel Pellegrini's side fourth in the Barclays Premier League table, a point behind United.
They head into the 165th Manchester derby in their worst form of the season, but that does not bother Kompany.
"A derby is a derby," he told mcfc.co.uk.
"It doesn't matter what place you are in the league, it's a derby
If anything, it's a good moment to go into a derby
"I guess the momentum is a little bit with our neighbours at the moment, but it's the perfect place for us to go and try to rectify what we've had."
While many are now writing off City's chances of defending their title and even speculating about their ability to hold on to a top-four spot, Kompany insists the players do not doubt themselves.
"We are demanding with ourselves because we have to win," he added.
"My only concern is we get back to our best form.
"I think it's our general form that we have to improve.
"I've learnt from the past seasons as well that finishing a season strongly can have an impact on your next season as well."
