Alfonso Sena Manterola (5 October 1886 - 6 August 1958) was a Spanish footballer who played as a defender for Real Sociedad.
[2] Together with Juan Arzuaga, he was part of the Recreation side that played in the 1905 Copa del Rey.
[3] In 1906, he left Recreation Club to join his older brother at Unión Vizcaino, and in that same year, the best players from Vizcaino and Athletic Club came together to form Bizcaya, which was specially created to take part in the 1907 Copa del Rey, and the Sena brothers were elected into the team, where Alfonso formed a defensive partnership with his former Recreation Club teammate, Juan Arzuaga of Athletic.
[4] On 24 March 1907, he made his competitive debut for Athletic (Athletic Bilbao counts the matches played by Bizcaya as its own) at the 1907 Copa del Rey, in a 3–2 win over Madrid CF,[5] and Sena faced them again in the final, but this time they lost 0–1, courtesy of a late goal from Manuel Prast.
[8] In 1913, in another edition marked by two parallel tournaments, Sociedad also played in one of the two Cup finals, this time against FC Barcelona, who needed three games to beat them.
