Jacques Anton "Sjaak" Alberts (27 February 1926 – 21 July 1997) was a Dutch footballer who played as a defender.

[1][2] Born in Arnhem, Alberts started playing football as a youth for Gelria from Velp.

Later, he moved to Vitesse where he made his senior debut in the first team of the Arnhem-based club at the age of 16.

He was 27 years old, until recently an international, and captain of Vitesse, which a few months earlier had become champions in the First Division of the East District.

Alberts was a defender who ten years after his debut decided to retire in order to focus entirely on a career outside football.
