I don't see Manchester city as a potential winner in the upcoming derby. Just like the instances you gave above. Manchester United has been having the upper hands in this derby lately and something similar can still repeat this time around. Manchester United have won their last two Matches, they are looking like a side that has rediscovered their form. I can bet that Manchester city will not beat Manchester United in the upcoming derby. I just hope that their players who are out on international duties should not pick up injuries. And Manchester city hasn't won in their last two matches. So there is nothing to fear. Worst that can happen is a draw, they both share the points.
Two consecutive wins by Manchester United mean absolutely nothing in the context of their form. To say that they have picked up form they need to win at least 5 matches probably. MU are in the second half of the table and are struggling, unlike Manchester City who have had a disappointing season but are in pretty good shape compared to MU
Manchester United looked motivated and seem to have discovered their form in their last two games, they performed fearlessly and like I always say Manchester United play better in big games like this. I won’t be expecting less from them against Manchester City so my prediction for that game is a win or draw in favor of Manchester United.
