Wilmer Santiago Acasiete Ariadela (born 22 November 1977) is a Peruvian football manager and former player who played as a central defender.

He also holds a Spanish passport due to the many years he spent in the country, mainly with Almería,[1] with whom he appeared in four La Liga seasons.

Born in Callao, Acasiete started playing professionally with Deportivo Wanka, moving in the following year to Universitario de Deportes.

He was an important defensive element in the Andalusians first-ever promotion to La Liga in 2007, being used intermittently in the subsequent seasons however: in his first top level campaign in Spain he appeared in only 20 games, but still managed to award his team six points with last-minute home strikes against Sevilla FC[2] and Villarreal CF (both 1–0).

[5] On 3 July of the following year, after an investigation and a review of the facts, the suspension was changed to three months (from the date of appeal in April) with a US$10,000 fine.
