It's unrealistic to go from mid-table for almost a decade to Scudetto winner and CL contender. Things just don't work that way and you're setting yourself up for disappointment. Look at how long it took Manchester City to get to to this level. They got wealthy owners from 2007 and current wealth doesn't even close to ours, supported not only by their owners but also the league revenue.
Our policy will most likely be to buy young prospective talents up to 30-40m max, for guys like Tomori/Tonali, etc. and tbh I even like it this way, as you get to witness the growth of the player. This year we have a small chance at the title, which took a huge blow coz of the injuries. Next year we'll be among the favorites and the year after that I expect us to cruise to 1st. In 4-5 years we will be a powerhouse and then start spending big on the few gaps we will have by that time, same as Liverpool did.
Management is doing everything right. If you're upset, it's 100% your fault. Please understand that and stop crying like a little baby
