Internacional have signed Anderson from Manchester United on a four-year contract.
Anderson, 26, was allowed to leave Old Trafford after failing to make an appearance under Louis van Gaal since August, and is reported to have made the move on a free transfer.

Anderson made an initial impact after joining United from Porto in 2007, scoring a penalty in the 2008 Champions League final shootout victory over Chelsea and then starting in the final against Barcelona 12 months later.
However, he only made 70 Premier League starts during his long and injury-hit spell at Old Trafford, and his only appearance in the league this season came as a substitute in the 0-0 draw with Burnley in August.
Before the completion of the deal, Internacional president Vitorio Piffero had told Radio Gaucha: "I'm sure he will be the Anderson that we all know."
Internacional defender Paulao, meanwhile, told a news conference: "I see Anderson like a developing player who uses the strength and speed he has and is creative."
United midfielder Juan Mata had already announced that Anderson, who had an unsuccessful loan spell at Fiorentina last season, was due to leave the club.
