In his period with
Cercle Brugge he scored 93 times in only 89 matches. His 1910–1911 season was especially remarkable, scoring 38 goals in 20 matches; half of the goals Cercle Brugge scored that season. In 1910, Six received his first cap for
Belgium, winning 3–2 against
the Netherlands and scoring once. Six played nine times for Belgium, scoring eight goals. Six still holds two Cercle Brugge team records: • An average of 1.045 goals per match. • Five goals in one match, against
R.E. Sport's Club In 1912, Six left Cercle for
Union SG. Due to Union SG not keeping their promises about a job for him - professional footballers were unheard of at that time - he moved to
Olympique Lillois, a predecessor of Lille OSC. That season he became the first Belgian football player to become a champion in a foreign country. ==Death==
