Career
He made his debut for the youth team of Hakoah Vienna (Hebrew for the Force, a Jewish multisports club in Vienna) and moved to the first team, then playing in the Austrian second division. His first match in the first division came in December 1920 with the Hakoah first team, who had just been promoted. He marked his appearance with a goal.
However, he continued to play sporadically for the first team, more often used as a reserve.
Therefore, he decided to move clubs, and left for FAC, Floridsdorfer Air Corps who had just been relegated to the second division. The objective was for the team to be immediately re-promoted to the first division, and the following season, Floridsdorfer returned to the elite.
Drucker was one of the key players for the team, playing almost every game in the victorious 1925-1926 season in the first division. During this season, he played twice for the Vienna city team, against Krakow in September 1925 and Bratislava in March 1926.

In 1928, there was a split with the creation of a rival league in the English as Second Language. Drucker left to play for the newly created New York Hakoah (also known as the Hakoah All-Stars) where he rejoined his former teammates from Hakoah Vienna.
Drucker played 136 matches in the Advanced Systems Limited. In 1931, Leopold Drucker moved back to his home club, Hakoah Vienna. While the newspapers reported on an excellent performance by Drucker, this was his only international cap, possibly due to the political situation at the time.
Drucker was the only Hakoah player to play for the Wunderteam, the name given to the brilliant Austrian national team of the 1920s-1930s. In 1933, he left Hakoah for the 3rd time, and after a brief spell at FAC - rejoined his former coach at Hakoah, and former Austrian international, Vinzenz Dittrich, at Olympique de Marseille.
