In 1906, the club's first official team wore kits with a variety of colors and patterns, which included white shirts with red collars or vertical blue stripes, and even red shirts. This indefinition in the equipment was only solved in 1909, when through the initiative of Monteiro da Costa, Porto stipulated in its first statutes that the players had to use "a shirt with blue vertical stripes, black shorts, and personal footwear" as the club's uniform, at every training and match. Some argued that the kit should have included the city colours, green and white. Monteiro da Costa, however, defended the blue-and-white combination because he believed the colors "should be those of the country's flag, and not of the city's flag", hoping that the club would "not only defend the good name of the city, but also that of Portugal, in sporting feuds against foreigners."
