Chabala was born in Mufulira where his father was a miner, the fourth born in a family of 12. He started out as a striker and played for Lubuto Amateur Club in Mufulira where his career in goal started by accident at the age of 17. During a practice session, the regular goalkeeper was absent so Chabala was forced to man the posts by his colleagues. He reluctantly agreed but played so well and enjoyed playing in goal that he decided to make the switch permanent.
