Sergio Paulo Barbosa Valente, popularly known simply as Duda, is a Portuguese international footballer who currently features for the Spanish Malaga. He plays as a left-winger.
Duda actually made his professional debut outside his home nation of Portugal. He began his career in Spain for modest side Cadiz in 1999 and after two seasons of great performance and perseverance, he was signed by Malaga for whom he featured in 93 matches in all competitions. He was on loan to Levante for the 2002-2003 season.
Sevilla signed the promising and hard working left-winger in the summer of 2006 but he failed to cement himself in the starting line-up regularly. Yet he received his first international call-up for Portugal in 2007 but has been able to add just 18 more international cap.
Duda was on the books of Sevilla until 2009, although he played for Malaga on loan in 2008-09. He scored five goals in 35 league appearances for them that season and earned a permanent contract with his old club in the summer of 2009.
Since then Duda has established himself as an important player for Malaga, helping them reach the top four of La Liga in the 2011-12 campaign.
