How are they losing if he's refusing to take his wages?
"Losing" refers to the revenue Milan lose because Kaká isn't playing. So they aren't losing because he's refusing his wages. They're losing because he's not playing. The question is whether his returning his wages covers what Milan believe they are losing with him out for a month (or whatever), which is why I speculated that they're probably insured for a sum greater than his wages.
Another way: Kaká costs the club €
n a month in wages, etc. It
may be the case that the club believe that having Kaká on their side, in terms of exposure, tickets sold, points won in matches, etc., is worth €
m a month. So if the club were to insure itself against an injury to Kaká, surely the value they would put on it is €
m a month, not €
n. Now it may be the case that
m =
n. But it's not crazy to assume that
m >
n. So with Kaká out, they pay him
n, but still receive
m from the insurer. With Kaká's refusing his wages, it'd be pretty slick if they now make
m +
n. But I don't know. Hence, I'm speculating.
