In 1996, da Silva reached the Primera División Paraguaya with Asunción team Presidente Hayes at the age of 16. Mexico Before joining Toluca, da Silva played for Perugia and Venezia of Italy, and Lanús of Argentina. He joined Toluca from Paraguayan Club Libertad for the 2003 Apertura. After making his debut, da Silva was a mainstay in Toluca's defence, starting all but one game that he has played and eventually becoming the team's captain due to his leadership on the field. In 2007, he was chosen for the "Ideal Eleven" squad of South America and in 2008 he led Toluca to the Apertura 2008 title, being chosen as the best overall player of the tournament by the Mexican media.

He is captain of his country and has played at the highest level in South America, so will bring leadership qualities to our side."

He made his debut on 24 August against Norwich City in the League Cup second round, playing the whole 90 minutes of a 4–1 away win. On 12 September he made his first Premier League appearance, replacing Steed Malbranque for the final ten minutes of a 4–1 home win over Hull City. Da
