The veteran midfielder has committed his future to the Girabola club and confessed he is looking forward to playing in the African country
The 39-year-old midfielder had been without a club after parting company with Sao Paulo last month and has reportedly agreed to a one-year contract with the top-flight outfit.
"I terminated my contract with Sao Paulo and I feel I have the ability to continue to play," Rivaldo is quoted by A BOLA as saying.
"I received offers from several countries, but I chose Angola because of the language and because I liked the project.
"I have been a champion in every country where I have played, I have always given my best for every club I have represented, so I am confident.
"I am sure that I will be happy at Kabuscorp and in Angola."
Rivaldo, who scooped the FIFA World Player of the Year award in 1999, has played for AC Milan, Olympiakos and AEK Athens, among other clubs, since leaving Camp Nou in 2002.
