just for the record, squad costs 2 years ago and now using the tables from the above calcioefinanza posts:
from 400m to ~270m overall, not bad. much more sustainable to say the least. quality is not fully there yet, and some of the tici deadwood (arthur, ramsey, rugani will cost us a modest ~39m this season, while they played ~100 minutes combined; let's hope arthur will become useful, no hope for the other two) will remain in the books for a while, and it's the last season for costa's amortization too, so there's still some room for improvement. i expect the new acquisitions of the following 2-3 seasons to have reasonable costs.
