The price tag is the disturbing part for everyone I think.
As I said though, a CL win is the pathway for me to view this move as a success. Anything less and at best this deal is just alright. (IE. CL semi's for next 3 years, Higgy scoring 25-30 per season, 3 scudetti)
As long as the second bit happens we cement ourselves as a top club in Europe again. But not yet the very best. A CL win is so necessary for that. I will not judge this transfer as a fail or success until at least the end of next season, and again at the end of 2 years.
Anyways. Worries are certainly justified. But melting down over getting a world class striker is silly. There's a middle ground. You and X are giving the perfect response. Measured anxiety over the price.
