The latest loss to Crystal Palace on Monday night left them nine points adrift of champions-elect Chelsea but the City captain refused to discuss the growing gap.
“For me, my only concern is we get back to our best form,” said the Belgian. “I???ve learnt from the past seasons as well that finishing a season strongly can have an impact on your next season as well.
“We have United on Sunday and a derby is a derby. 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 on Monday.
“It???s hard to draw too many conclusions from many of those recent away defeats.
“Credit to Crystal Palace but that game was not one I felt we should have lost. It has a bit of a different feel to it maybe than, say, the result at Burnley.
“But a team like us needs to win and that wasn???t the result that we hoped for.”
