If Manchester United don't want to give Manchester City a win, then Manchester City players will dig out the win from them. Manchester United are not leaving Etihad stadium with a point this is one thing I can assure you. Of a truth Manchester City needs this point more than their neighbor and we are going to see many goals in this game. If not for anything it's a derby game and there is joy when you win your neighbor.
It will go very wrong for Manchester United this season, especially in tomorrow's derby match. Because if Manchester United is able to prevent Manchester City from getting full points in tomorrow's match, of course that will be an even greater advantage for Liverpool to make a point gap with Manchester City this season. So Liverpool has the possibility of getting their 20th Premier League title and will equal the Premier League title achievement that Manchester United has had during their career in the Premier League.
There is always the possibility of surprise results in derbies. Manchester City is the favorite in the match, but Manchester United also has a chance to win the match. Therefore, it might be better to look at what kind of football they are playing in the first 10-15 minutes of the match and comment on which team will win. Derby atmospheres are very different and teams cannot always play the game they want in derby.
I do not think that a team competing for the league championship will lose points, even if it is a derby. Before the match starts, I think City will win, but my decision may change after watching the first 10-15 minutes of play. I think it will be a match with lots of goals.
