Marcelo de Mattos Terra is a professional football player from Brazil who plays as a midfielder. In 1997, Mattos began his playing career at Mirassol, a third-division team. He broke into the first team squad in 1999, staying with the team till 2001. During that period, Mattos played well enough to garner attention from FC Tokyo, in Japan.
He moved to Japan in 2002, but after just one game, moved on to Oita Trinita. Throughout 2002, he played just 2 games in Japan and returned to Brazil to join Sao Caetano in 2003. After a decent season with the club, he moved to Corinthians where he came into the form of his life. A fantastic holding midfielder, Mattos made the position his own and played over 130 games for Corinthians, scoring 17 goals, over a period of three seasons.
He played a vital role in helping the team win the 2004 Sao Paulo State League title as well as the 2005 Brazilian Serie A title. He came second in the race for Player of the Year for the 2005 Serie A season in Brazil.
In 2007, after completing his contractual obligations, Mattos moved to Panathinaikos in Greece, where he slotted into their central midfield. After playing over 50 games for the Greek side, scoring 4 goals, he was sent out on loan, back to the Corinthians, for 2009-10. During his loan spell, he failed to recreate his magic, and his dip in form, which led to the loan in the first place, continued.
After 18 games, he returned to Greece but was, soon after, sent on another loan move, this time to Botafogo for 2010-11. He played 25 games and scored a goal, however it was his ability to control games that got Botafogo interested in a permanent move for Mattos. In 2011, he signed a contract with Botafogo and is a regular member of their first team squad.
