Sao Caetano land Rivaldo
The 2002 FIFA World Cup™ winner and 1999 FIFA World Player of the Year, now 40, will return from a spell with Angolan side Kabuscorp to play in the Sao Paulo state championship and the national second division.
Club president Nairo Ferreira de Souza told the club's website: "It is a significant reinforcement that will give a refined touch to our midfield. His technical quality is fantastic and he will greatly help the group with his experience and leadership."
Rivaldo himself wrote on Twitter: "I thank God that for 40 years I have the opportunity to continue playing. I had offers from several clubs and I'm happy.
"To critics I would like to say that this is only a result of my dedication and I will be working hard to do my best on the pitch. I hope to be an example for many."
