There are no tax breaks for footballers anymore in Italy and tax rate at that level is over 40%
Only players that benefited from the old tax breaks(like Lukaku, Leao, Thuram) can still take advantage of those provided they don't work more than 1 year out of Italy, or something along those lines
Nobody in Italy can afford his salary. Or better yet, nobody is going to be willing to pay him that much. The good news is that he's in the final year of his contract. The bad news is that if you even manage to get a transfer fee, it will probably be just enough to cover the difference in wages for the season
And Di Marzio is gospel when it comes to Italian clubs and players
