The nickname Kaká, from his native Portuguese, is pronounced as it is  spelt. The accent would signify that the stress is on the second  syllable. In Italian, the language of his current team, the phonetic  equivalent is written as Kakà, which is used for Italian television  graphics. However, the player's shirt name is spelt KAKA' (with an  apostrophe, rather than an accented 'A') for both Brazil and Milan.  An internet discussion forum explains the nickname as a commonly used  shortened form of "Ricardo" in Portuguese. Kaká is supposed to have got  his nickname because his little brother Rodrigo could not pronounce the  word "Ricardo" when they were young. Rodrigo called his older brother  "Caca\ Kaká suffered an accident when he made a faulty jump off a diving-board,  resulting in a vertebra fracture. This could have meant the end of his  football career, but he believes that Jesus allowed him to recover and  become the successful footballer he is now. When AC Milan won the Serie A  title in 2004, Ricky, as he is called by his team-mates, sported a  shirt with an "I Belong to Jesus" slogan. He also points his fingers to  the sky as a sign of thanks every time he scores, for apparently the  same reason.
