Rafael, who started his career with Figueirense, played for the likes of Vasco da Gama and Avai FC in Brazil besides having the experience of playing in Asia.
He featured for Guangzhou R&F Football Club and Changchun Yatai FC in the Chinese Super League besides having a spell with Buriram United Football Club in the Thai Premer League.
Head coach Zico is yet to access the new striker about when the player is able to play his first game for FC Goa after arriving from Brazil yesterday.
Darryl Duffy has suffered from a hairline fracture to his shin in the match against Mumbai City FC, Reinaldo has an ankle injury and Victorino Fernandes has a groin injury while C S Sabeeth too is not a 100 percent.
This leaves Zico with the options of Joaquim Abranches, who has not played a single match this season, and Thongkhosiem Haokip currently available at his disposal.
"I am very happy for the opportunity to be here. All my team-mates received me very well. I hope to give my best and help the team to become champions. I have a lot of trust and confidence in the team after seeing how the team is working very hard and I hope to do my part as well," said Rafael.
Zico too had earlier acknowledged, "It is a pity because Victor Simoes is such a good player. I know him for so many years. We tried to help him recover from his injury. We will miss him in our team because he could have been a very good asset.
