Futebol Clube do Porto is a Portuguese sports club based in Porto that is best known for its professional football team playing in the country's top-tier division, the Primeira Liga. Founded in 1893, the club soon entered a period of inactivity until its revival in 1906 by a group of people led by future president José Monteiro da Costa. The following year, Monteiro da Costa invited Adolphe Cassaigne, a Frenchman, to become the football team's first official head coach, replacing Italian player-coach Catullo Gadda.
