With the poor performance of City yesterday, I don't think that they have a better chance of Winning United in the upcoming Manchester derby because, City does not have the quality you think they have anymore, and United might shock you on that day by winning City. I see the game as 50-50 in favour of none of them.
For now Man City can't do anything to fight for a good chance in every match and even against Man United, people will definitely say the same thing that the chances are unpredictable. And for my temporary prediction, Man City has a slight advantage when playing at home. If Man City has difficulty beating MU, maybe a draw will be the best result for both teams.
You are right in this prediction because a Manchester derby is unpredictable but in the way both teams are struggling to gain their form back I think a draw might also be a good result for both taem, but still I think Manchester city has a stronger and talented players than Man Utd so if there is a probability of winning it will be Manchester city but will not be surprising If man Utd wil win the match, looking forward to the Match this weekend.
