Maroso played as a defender. After a period on loan at Alessandria (1944), he made his club debut with Torino on 14 October 1945, in a 2–1 defeat to rivals Juventus in the Turin Derby. In total, he played 103 times for Torino in league matches, scoring once, and won four consecutive Serie A (scudetti) titles between 1945 and 1949.[1]
International career
At international level, he was capped seven times for the Italy national team between 1945 and 1949, scoring one goal. His debut came on 11 November 1945, in a 4–4 draw against Switzerland.[1][2]
Style of play
A promising and highly talented player, Maroso was a precocious full-back, who is considered to be one of the best Italian players ever in his position, and is even rated by some pundits in the sport to be Italy's greatest left-back ever. A fast, powerful, elegant, and technically gifted offensive-minded left-back, who was known for his flair and touch on the ball, Maroso was one of the first-ever attacking full-backs in football, and was even capable of playing as a winger due to his ability to get up the flank; although he stood out for his attacking prowess, he was also strong defensively, courtesy of his foot-work and anticipation, and was capable of playing with either foot. In addition to his playing ability, he also stood out for his correct behaviour and fair play on the pitch, and he rarely gave away fouls; despite his skill, however, he was also injury-prone.[1][3][4][5][6]
