I get your point, and it reminds me of the time Alphonso Davies said in an interview that when he saw Thomas Müller playing, he couldn't understand how he could be a professional football player for Bayern München. He doesn't have strikingly obvious qualities like dribbling, strength, passing maestro or pace, but it's the combination of being decent in every aspect in addition to his football intelligence and usage of space that makes him excellent. I'm not saying Mount is as good as Müller, but I think they are a bit similar in how they are perceived by fans, and the fact that Mount doesn't have a quality he is world class in, he is perceived as a nothing player who doesn't really contribute anything to the team or a game, even if it's very wrong.
I think he is very good at just keeping the game ticking, trying to keep the momentum and intensity up (unfortunately, he can't do it by himself - we are very badly coached in terms of high intensity pressing as a team). He is a decent enough passer who is very good at linking up with players. The problem here is that our players aren't used to play like that. We have relied on individual brilliance and moments for a very long time, so instead of building up an attack, making runs in midfield to provide space and opening passing lanes, they are passengers who jog around waiting for each other to create something, but that's just not going to work consistently in the PL if our ambitions is to win the PL.
I don't really think he is the answer to our problems, as they go far deeper than a player, but we should absolutely give him more time and let him play, especially with the form Bruno is in. You simply cannot let players who perform bad continue to play every game with no consequences. Either way, he is a good and useful player, but just not what we really needed.
