Kaka: I was afraid that my career could be over © EuroFootball.com

The security guard of Real Madrid Kaka admitted that after suffering a serious road injury, he was afraid he might have to end his career.

Brazil returned to the pitch on Monday in a match against "Getafe". It was his first appearance since the World Cup quarterfinal match against the Netherlands in July.

"At times, I was afraid because I didn't know when I would step back on the field and if I could even do it at all," said Kaka. "I was missing the joy that I get from playing. Now I can play again, so I will try to do everything to be happy once more."
