The ninth season in the first, '65 -'66, became the best in history. STVV literally and figuratively shot out of the starting blocks: 23 on 24 and autumn champion.

Sint-Truiden was suddenly the epicenter of Belgian football. Bosmans, Martens, Polleunis and Vandeboer were called as A-or B-international and the Spanish Football Association invited the Canaries for a friendly match against the national team.

Yellow-blue lost 5-1, but the season could no longer be broken. STVV closed the season as vice-champion on 7 points from Anderlecht.

The wizard Raymond Goethals, who played a very important role in this success, left STVV to become national coach.
