“I feel like I was chosen by God.” That is how William describes his journey in the world of football. He is is true example of how to apply yourself both on the pitch and off it. Born in Angola, he arrived while still young in Portugal and began his career in Algueirão. A move to Mira Sintra followed, where he attracted the attention of scouts from the area's main clubs. When decision time came around, his idol (Nani) was playing for Sporting, so William headed for Alvalade.
He began in January of the 2006/07 and won the regional and national championships in his age group that same season. Another championship double came the following year, before he made his senior debut in 2010/11 against Guimarães, coming on for Matías Fernández in a 1-1 draw.
As a senior he was loaned out to Fátima and also spent two seasons with Cercle Brugge as an attacking midfielder. In 2013/14 the then coach Leonardo Jardim brought him back to Alvalade, where he has gone on to earn his place as a holding midfielder and tally a notable collection of individual awards. Making 33 appearances in 2013/14, he put in his best season yet in 2014/15 and was instrumental in Sporting's Portuguese Cup win. As well as featuring for the Portuguese national senior side, he was also a constant in the under-21 side at the 2015 European Championships.
