Diego Ribas da Cunha (born 28 February 1985), also known as Diego, is a Brazilian professional footballer who currently plays for Werder Bremen in the Bundesliga. He has played over 20 times for Brazil. Born in Ribeirão Preto, São Paulo, he was signed by the São Paulo team Santos FC at the age of 12. Diego developed in the Santos youth system, making his first team debut at the age of 16 in the Rio-São Paulo Championship in 2002 and in the same year he won the domestic Campeonato Brasileiro championship. Diego was called up for the Brazil national squad for the Copa América 2004 tournament, and he was instrumental in securing the tournament victory for Brazil when he scored in the penalty shootout against Argentina in the final. He and Robinho were known as a famous duo when they played for Santos FC.
Diego almost joined Tottenham Hotspur in 2003 but the move collapsed at the last minute when the Santos FC chairman refused to sell him.
He was transferred to Portuguese club FC Porto in July 2004. Diego did not maintain a stable place in the Porto team under coach Co Adriaanse. And because of that, Diego was left out of the Brazil squad for the 2006 FIFA World Cup tournament. He was though a substitute in a friendly match against England on 1 June 2007, and scored a last minute equaliser.
