We've already seen what it looks like, when we have someone as bad as de Gea. It started with Mourinho's final season and continued during Ole's 2 full seasons. I'm not even going to comment about his complete reluctance to come off his line or how his passing has gotten worse over the years. Purely from a shot-stopping persepective, he's had 3 bad to average seasons following his unreal season in 2017/18, which wasn't sustainable. This season, he's having another shot-stopping season that isn't sustainable, as he himself has shown.
These quotes are perplexing from a certain point of view. I'm constantly reading, how we now have structure in place that has a clear idea, how we want to play. Which is supposed to help the new manager and should we transition from one manager to another, so that a managerial change isn't that much of an issue as it used to be. On top of that, it's supposed to relieve responsibility from the manager by delegating certain tasks like the recruitment, for example. And yet, particularly the first tweet/quote reads like Rangnick doesn't think it has changed all that much, at least not yet. Furthermore, and I'll probably sound like a salty muppet here, but if we actually do have that structure in place, irrespective of who the new manager was/is going to be, then why weren't we in for Bruno Guimarães? The whole point, among other things, of Murtough and his team is supposed to be to bring in players that fit a certain style of football that we are trying to play with the hiring of ten Hag. Moreoever as Rangnick says in the third tweet, certain players are suited to different styles of football, so regardless whether we hired Conte or ten Hag, Bruno Guimarães would have worked for either, since he has range of qualities/attributes that both managers despite their different styles could use. Which then leads me to question, how good our set-up behind the scenes actually is, if they can't make the most obvious signing.
