On his return Miller brought some association football equipment and a rules book with him. He then went on to develop the new rules of the game amongst the community in São Paulo. In 1888, six years before his return, the first sports club was founded in the city, São Paulo Athletic Club. São Paulo Athletic Club won the first three years championships. Miller's skills were far and above his colleagues at this stage. He was given the honour of contributing his name to a move involving a deft flick of the ball with the heel "Chaleira".
