It was a sad day when money bought humility and loyalty.
That's what Madrid got when they spent an immense amount of money on Kaka. They managed to take possibly the most true and good player in the world, and, via financial methods, force him to leave his home and play for them.
In Kaka's interview where he spoke about his transfer, he defended the club. Yes, the club. The club that he loved, which in turn sold him. He stated that his transfer was best for the club because it helped restore some of the financial security that Milan have been lacking.
Kaka's transfer was Milan's sacrificing him for the greater good. Like many, I had always envisioned Kaka one day captaining Milan, possibly as soon as next season—unfortunately that will never happen.
However, don't doubt for a second that Kaka is a Milan legend. He gave six years of devoted service to Milan, during which he almost single-handedly won them the Champions League in 2007 before shutting the transfer door in the face of Manchester City, who were offering to pay Kaka an exorbitant amount of money.
He is aware that he got sacrificed, and he is okay with it because, even though he no longer gets to shine in the sacred red and black strip, he did what was best for the club that he loved. And so, even though he now plays for a rival club, don't doubt for a second Kaka's status as Rossoneri legend.
