During his first competitive appearance in his second year with the club, Pulisic became Dortmund’s youngest player ever to play in the UEFA Champions League. Quilmes did not qualify to play there so the team continued at Primera B, which became the third division after the restructuring. In 1986, due to a major restructuring in the Argentine league system, a new division, “Primera B Nacional” was created. In 1980 Quilmes was relegated to Primera B, returning to Primera just one year later along with champion Nueva Chicago after finishing 2nd. Quilmes made a great performance during the 1981 Nacional reaching the finals where the team was finally beaten by Ferro Carril Oeste.
