Manchester United are a big club and indeed they have players like you said but in this case their performance is much different and even now of course City are very favourites even though it is Derby.
Personally, I actually quite like Manchester United, especially considering their current players, but their performance is far from good at the moment, which makes me not so sure they will give a meaningful resistance.
Although Man United isn't in a good shape, they may surprise us like Tottenham beating City. Man United has good players, especially in the attacking line, they can win if they use a counter-attack strategy. It is what Tottenham ever did, they won in City home because City too focus on attacking. Man United players can take advantage of the same situation as Tottenham ever faced. Although City is the favorite team, I still think they can have difficulty facing Man United players.
Yes, Manchester United could use a strategy like the one that was successfully applied by Tottenham against the same team, Manchester City. But Manchester United are not a good enough team to use a counter-attack strategy. Indeed, Manchester United has a Ronaldo who is experienced and famous for his deadly counter-attack when he was at Real Madrid. But that's not enough, because in Real Madrid he has support that can work well together like Benzema and Bale.
What you say is quite reasonable, it seems difficult for Man United to beat Man City with the strategy used by Tottenham. Because of the strategy used
by Tottenham, which relies on a disciplined defense and counter-attack. It requires solid cooperation between players, which Man United has not had
so far. Even though the Man United squad is much better when compared to Tottenham, but the problem is that Man United players are too selfish and
can't have good cooperation between one player and another. Every Man United player relies too much on individual ability. So it's not a good idea
if Man United rely on the same strategy as Tottenham.
Rangnick must think of another strategy that suits his player character. Unless Rangnick can control his star players firmly, then Rangnick can make
Man United players have a good cooperation. So Man United can use the same strategy as Tottenham. Actually, there is no need to follow
Tottenham's strategy, if Man United players can have good cooperation, whatever the strategy is, it is possible to beat any team, including Man City.
Because it is not easy to control the star players at Man United, looks like Man United should have a coach like Xavi or Arteta who dares to act decisively,
to star players who break the rules and can't be controlled.
