Eugenio Esteban Mena Reveco (Spanish pronunciation: [euˈxenjo ˈmena]; born 18 July 1988) is a Chilean professional footballer who plays as a left-back for Brazilian club São Paulo FC, on loan from Cruzeiro. He also plays for the Chile national team.
Mena finished his formation in Santiago Wanderers' academy, and made his senior debuts in 2008 Chilean Primera División B. He scored his first professional goal on 11 October 2009, against San Marcos de Arica.
In July 2010, Mena signed with Club Universidad de Chile, for a $500,000 fee for the half of his rights. In his first season, Mena failed to break into a settled squad, appearing rarely. However, after the arrival of Jorge Sampaoli in 2011, Mena was converted into an important player of the La U squad. At the end of the season, he was a part of the squad which won Copa Sudamericana and Chilean Primera División.
On 3 July 2013, Mena signed a one-year loan deal with Brazilian Série A outfit Santos FC, with a buyout clause. He quickly established himself as a starter, and on 5 June of the following year Peixe bought the remaining rights of the player.
