He's only a flop because we're not playing him, not because he has failed to justify his price via performances... like say... Fred...
I mean, VDB has performed the few minutes he's gotten this season, too. But unlike McTominay he doesn't get to start after he performs. See the difference?
Supposedly, not supposedly, the fact of the matter is that this "competent" manager is not doing too well, is he? Just like our previous one. So your argument is totally moot when two managers that have failed to give Donny minutes are failing. If it was the other way around, and if Rangnick actually made something out of Matic, or Fred, or McT nobody here will give a rats ass about Donny or whoever. But the fact is we're still suffering from the same old problems that we did under Ole.
First off, because Donny has earned his right to get a few matches based on his performances this season. Second of all, because quite clearly a midfield of Fred/McT or Matic isn't working whatsoever. So why not try something else? Maybe it'll fail, but we're already failing now regardless. So what's there to lose? Or is your idea of good management is to just let the ship sink without doing anything? "Oh well, McFred are useless but Donny couldn't be any better so let's just die". That's a defeatist mentality. I rather this team go down fighting with a roar than with a murmur. If that means to play the fecking kids, you play them, I don't care. Obviously something needs to change in this squad and the midfield is our most glaring weakness. Villa passed us around like they were prime Barcelona. And it's not only Villa, United make every other team like that, too.
