Furthermore, Manchester United will be facing City and Nottingham Forest, as you said, and this is going to be a difficult one for them, seriously, because Manchester City are doing better than Manchester United currently.
Manchester derby will always be different. Although Man City is currently better, this match will be at United's home ground. Even their last meeting United won.
The current situation may be different, because we know Man City is also better than the last meeting between the two. It will still be a tough match, but Amorim may not let them lose this time. If they can't win, maybe a draw is not bad for United.
