It was supposed to be a tough match because Manchester City and Manchester United are big clubs, and it is also a derby match that both clubs want to win to prove they are the kings of Manchester. When it comes to the Manchester derby, Manchester City always wins easily against Manchester United. Haaland will perform better than Hojlund because Manchester City will dominate the match and create more chances, while Manchester United will play defensive football and depend on a counterattack to score goals.
It's not only Haaland will perform better than Hojlund, but Hojlund is currently injured, Manchester United would be forced to let Rashford become a striker, unfortunately Rashford is a bad striker. So it's a clear win for Manchester City, even Manchester United has a full squad, the chance to win is still low.
At least Manchester United should prevent to be humiliated
