Diego Ribas da Cunha (born 28 February 1985), commonly known as just Diego, is a Brazilian professional footballer who plays as an attacking midfielder for Brazilian club Flamengo.
Diego began his career at Santos, where he won two Campeonato Brasileiro Série A titles before moving to Porto in 2004. Despite winning further trophies in Portugal, his personal form dropped. After two seasons, he moved for €6 million to Werder Bremen where his form improved, winning domestic honours and helping them to the 2009 UEFA Cup Final. He also won honours at Atlético Madrid, including the UEFA Europa League in 2012.
A full international for Brazil since 2003, Diego earned 33 caps and scored four international goals. He was part of the Brazilian squads which finished as runners-up at the 2003 CONCACAF Gold Cup, won the Copa América in 2004 and 2007, and earned a bronze medal at the 2008 Olympics.
