The tactic was that Gilberto would run on the side of the pitch and then cross the ball at the end to Flavio who would score with a header.

With Al Ahly, Gilberto played against many world class teams such as FC Barcelona and Roma.

On 26 July 2015, during a match of Benfica de Luanda, Gilberto was knocked out following a tackle by an opponent from Progresso do Sambizanga.

He subsequently remained unconscious for about twenty minutes, before being resuscitated by medical service and immediately carried to the hospital.

In the 2010 African Cup of Nations opening game against Mali on 10 January in Luanda Gilberto made assist for 1–0 lead to Flávio Amado in the first half.
