Regarding the original post I had quoted, which is basically about big money moves and the divisive opinion, only Martinez/Antony, AWB and Casemiro applies here. Martinez/Antony came with glowing rave reviews from Ajax fans and incredible stats, Casemiro's achievements are enough said even if there were a few but consistent murmurs of age/last paycheck and AWB was a young english talent, who had shown insane athleticism and growth after 1 year in the PL. At worst, the opinion was 50 (in favour/not negative)/50 (not keen/negative) for those.
With Mount it feels 40/60 and it feels more pronounced because (I'm assuming) the majority of the one's not too keen on the move have unlike the above transfers mentioned actually watched him way more regularly in the league and internationally. So in some ways, it's comes from a more informed opinion. That's all I have to say about that because it's done deal now.
My personal opinion is that it feels like an opportunity lost where the floor is definitely raised but not the ceiling. I fully expect Mount to perform 'well' but then I expect our team to perform well anyways after a year of growth under ETH with hopefully better game managing from him/the players and the fact we now know where we stand as a team; it also doesn't hurt that individually we will have the superior players to the opposition 80% of the time. I'm a bit sour but I suppose if I took a step back and realise, perhaps if Mount helps us beat those teams more convincingly (against those said 80% of other 'lower' teams), then it will certainly be another level of progression that I can't be unhappy about. It's just the other 20% and taking another transformative step I was hoping for (not as one single player of course but even then I feel his potential influence seems to be on the lower end).
