What do you expect! You can't find a player with under 2m salary unless you recruit from the football school and 9 or 10 years old baby. It's 2025 please grow up.
Dude, there are many players of his level who are well under 2m... Even in our own squad, Cabal for instance.
Even a starter like Gatti was around 2,5m (don't know how much it is now after his extension).
My guess is you're overestimating Rugani. He can stay as a sub for all I care but he's not a solution to anything. We need another fucking quality defender and if either one of subs leaving (be it Rugani or someone else) can make that happen, do it.
A nice stat: there are 10 teams who don't even have 1 player with that salary in Serie A this year and 2 other teams who only have 1 of those. On top of those 12 Fiorentina's 2 best paid players have exactly his salary. So yeah, for what he brings and how little he plays, I don't think that's "cheap".
