Gregorio Sena Manterola (8 September 1890 – 22 May 1956) was a Spanish footballer who played as a midfielder for Real Sociedad and Athletic Club.
Born in San Sebastián, he began his career in 1909 at his local club Real Sociedad, which had just been founded by, among others, his two older brothers.
At the time, the teams who had not been legally registered for more than a year could not play official matches, and therefore, in order to play in the 1910 Copa del Rey, they borrowed the license from Vasconia de San Sebastián, under whose name they competed and reached the final, which they lost 0–1 to Athletic Club.
[2] In 1912, he joined RCD Espanyol, but after a brief successful spell he returned to Sociedad where he played until 1916, when he decided to retire at the age of 26.
He featured in the final alongside the likes of Domingo Acedo, Pichichi and José María Belauste, but still they were beaten by FC Barcelona.
