Having grown through the ranks of Vitória de Guimarães, Porto-born Duda had not yet played one single competitive senior game when he was sold to Cádiz CF in the Spanish Segunda División B.

[2] For the 2001–02 season he switched to La Liga with Málaga CF and, after a loan move to Segunda División with Levante UD, was everpresent in a team that achieved two consecutive 10th-place finishes, also appearing in the UEFA Cup via the Intertoto.

[6] During the season, he was an instrumental attacking element as the side narrowly missed on Europa League qualification, with compatriot Eliseu often playing in the other wing.

In late August 2009, after intense negotiations, Duda moved permanently to Málaga on a four-year contract, with Sevilla benefitting from a percentage of any future sale.

[13] In 2011–12, following the summer signings of Santi Cazorla and Joaquín and the ostracism to which Manuel Pellegrini voted Apoño after the first matchday, Duda was often used as a central midfielder.

[21] Duda made his debut with Portugal in 2007 at the age of already 27, as the winger position in the national side was packed with talent (Nani, Ricardo Quaresma, Cristiano Ronaldo, Simão Sabrosa).
