Forlano began playing for Juventus, with which he won the Italian title of 1905 — the first in the history of the club — scoring three goals in four appearances during that tournament. With the Juventus, he played six championships scoring a total of four goals in 17 matches. After two years in the ranks of U.S. Torinese without taking the field, in 1908 he moved to Milan. He made his debut with the club on 17 January 1909 in the 1–3 away league match against US Milanese; this was his only match with the club. In the final part of his career he also played with Stresa; the Stresa stadium is named after him.
