[8] On 16 August 2008, Djaló scored both goals in Sporting's win against defending league champions FC Porto to claim the Supertaça Cândido de Oliveira for the second year in a row.

[10] On 26 August 2010, Djaló scored in the 90th minute to help the Lions defeat Brøndby IF 3–0 after losing 2–0 at home, thus qualifying for the UEFA Europa League group stage.

[16] Two weeks later the appeal was rejected, which meant Djaló would not be eligible to represent a new team until January 2012; on the following day after the CAS ruling, Fournier confirmed to Portuguese radio station Rádio Renascença that the player would be returning to Sporting.
