Returning to Portugal, he shined in the CIF, at the beginning of the 20th century, as captain of the team and his coach, with innovative methods of training, managing to form the so-called wonder team. As a coach he was a studious and methodical, having introduced into the CIF the famous "theory of triangulation", which years later came to be implanted in Sporting Clube de Portugal. According to his conceptions of football, Augusto Sabbo argued that players should not make moves according to the circumstances, but rather make a movement that forces the opponent to execute the movement that interests us to be done so that the bursts happen as we imagine.
National coach
In 1921, he was chosen to be the first National Coach, but the players did not like the hardness of his methods and he ended up not guiding any game of the National Team. He came to command the Sporting teams in the season 1921/22, probably in January, still in time to participate in the conquest of the 3rd Lisbon Championship in the history of the Club and in the first Portuguese Championship Final, that Sporting lost in an epic final with FC Porto. The season of 1922–23 was a golden time, with the first victory in the Portuguese Championship and again in the Lisbon Championship. He remained at Sporting until February 1923, when he resigned after the Technical Council had denied him the freedom to form the teams, but returned at the beginning of the following season, resigning again in February 1924. In 1923, Sabbo edited in Lisbon a detailed 75-page manual titled Football , on all the important aspects of football. He would return to Sporting in 1926 becoming the first paid coach of the Club, but in time of crisis he was dismissed in January 1927, because the attendance of the players to the training was very reduced.
School
He then went to Barreirense, where he created the famous "school" of that popular Barreiro club, which managed to lead to two finals of the Portuguese Championships. In addition he was a referee and was part of the first teams of rugby of Sporting. He died on 30 October 1971.
