The Brazilian superstar arrives in the Spanish capital from AC Milan, having also just won the Confederations Cup with his national team.
This event will bring to an end a chase for Kaka's signature that has taken Madrid years, but one that has finally borne fruit.
The Blancos are well-known in the sport for their love of pomp and circumstance, and with thousands of fans expected to turn up to see president Florentino Perez hand over the white shirt to his latest capture, there is bound to be no shortage of a sense of event.
Goal.com will bring you the latest coverage from the Bernabeu live as it happens, so join us on Tuesday evening for your first look at Kaka in Spain.
