Their culture are different, Manchester City's culture is play for team regardless there's a star player or not. But Manchester United's culture is play with ego and seniority, since both Bruno and Rashford are old players, they deserved to get ball than the striker.
Hojlund is just a junior player, maybe Bruno is working together with Rashford in order to destroy Hojlund and Rashford will back as a pure striker.
Clearly this is what Plays out with Manchester united most of the time, they play with so much ego and tend to give few or no privilege to younger or junior players and this culture of theirs is really telling on their performance so far because these young talents become less optimal.
Bruno Fernandes happens to be one who exhibits so much of this attitude, some times I think he places his personal interest over that of the team thereby reducing their chances of winning in some of the match, hojlund is a very good player which if such team spirit found in Manchester city could be replicated at old Trafford, he will definitely thrive way beyond his current state but then the bigger boys still wants all the glory to themselves.
Maybe this is also where Manchester United's weakness lies. The seniority and selfish attitudes that occur between fellow players make this squad very bad at working together. In fact, news about internal conflicts between fellow players during training also emerges most often from this club. In fact, if they can reduce their selfish attitude a little, this club will become a strong team, maybe even able to match Manchester City. Because Manchester United actually has no shortage of star players. It's just that this club really lacks chemistry between the players. All players are too eager to stand out alone. They fight to become stars on the field and sometimes forget important points in football. Namely cooperation.
And whether this is just my assessment or others too. However, I feel that even Ten Heg as a coach also has a slightly selfish attitude. So it's not surprising that the players at the club do the same thing. But strangely enough, when every player at Manchester United returned to their respective national teams, it turned out that these Manchester United players were unselfish players. In fact, I see that Bruno Fernandes is also a person who is able to build very good chemistry in the Portuguese national team. Or maybe because in the national team there are many players who are more senior than them. This makes them stop being selfish and allows them to play better. I don't know, but what is certain is that Manchester United actually has very good potential if they can work together and not be selfish on the pitch.
