If Mount had any of the attributes at all to play in midfield I would be willing to be less skeptical, but he doesn't, and against Wolves and in pre-season he hasn't even been positioning himself in remotely the right place to play in midfield, he has been a second no10 alongside Fernandes...so its a two fold problem a) Mount isn't a midfielder, and b) ETH isn't using him as one. He's using Mount to play a system that simply isn't going to work. So we have to go through the process of both learning the system doesn't work, and then learning we need to sign another midfielder to play a system that does.
Its not based on one league fixture and a pre-season is it? We've all been watching football long enough to know playing with one midfielder in the PL is a very bad idea. Maybe ETH has a master plan to eventually make it work, but I wouldn't say its at all knee jerk or ill judged to be extremely skeptical of that, because there is literally nothing to base any idea it will work on, and a mountain of evidence to show that it wont.
Mount has been playing for Chelsea and for England for quite a while. He hasn't cropped up over night as this unknown player with unknown qualities. He's a no10/inverted wide player who covers a lot of ground and can be dangerous around the edge of the box. You know this, I know this. If we needed a midfielder what would make sense would be to sign a midfielder who's good at midfield stuff, not sign someone who isn't and just hope he'll learn ho to play there. He's been signed as a second no10 to play the system we used against Wolves. ETH could realise the system doesn't work tomorrow, but then he needs to sign a midfielder.
