As tactically astute as Rangnick is as a coach, I don't think United has enough fire power to go toe to toe against City. Ronaldo isn't really doing well. At least not as well as how much the club his paying him a week. They should drop him imho. And been hearing that Maguire hasn't been what he was expected to be. Dunno, seems like there's still some issues that needs some fixing.
From my point of view, City is gonna win, they're going to win without conceding and they'll do it by scoring a goal or two in the second half. IMHO.
Ronaldo plays worse than before because of his age - that's a fact. But his salary is determined not only by the game, but also by his name. At the moment he is one of the greatest and most recognizable athletes in the world and brings United more money than he spends on him. Another question is how much playing time should be given to him without compromising the club - this is a difficult question because even an older Ronaldo, when in good shape, plays better than other young strikers.
True, when looking at salaries, of course, apart from looking at their current performance, they also definitely take into account the big names there.
Ronaldo is one very big player and the era he is still around is starting to dim at this point.
Talking about performance, even when compared to other young strikers, I prefer him even though this is not a good thing to compare, for example comparing Ronaldo's performance to Hazard at Madrid or Grealish at City, I personally still highlight Ronaldo here
