Nice money laundering there by Inter and Chelsea for Lukaku. Buying him and selling him for ridiculous prices, which also helps with gross wages due to Italy’s tax laws.
the tax savings are nice, but it should allow Italian clubs to afford better players rather than overpay the same ones they'd probably get without this advantage.
btw the di Maria numbers are interesting - if he stays 2 years, total cost for the club is 15.7m, if he stays 1 year it's just 4.5m less - 11.1m.
