Born in Buenos Aires, Montenegro began his professional career at Club Atlético Huracán in 1997. He subsequently signed for Club Atlético Independiente, going on to represent the club on three different spells and teaming up with sibling Ariel in the first.
In the 1999 January transfer window Montenegro moved to France with Olympique de Marseille, being loaned several times by the Ligue 1 side for the duration of his contract, namely to clubs in Spain (Real Zaragoza – where he contributed with four matches to the club's conquest of the Copa del Rey – and CA Osasuna, both in La Liga). He then played in quick succession for Independiente and Club Atlético River Plate, before spending parts of two seasons in the Russian Premier League with FC Saturn Moscow Oblast.

In 2009, he moved abroad again, signing with Mexico's Club América for $3 million after lengthy negotiations; he made his unofficial debut vs Chelsea in a friendly, and made his officiail debut for his new team against Deportivo Toluca FC, scoring from his own half in a 7–2 routing.
