After an initial period in Los Andes, Maidana transferred to Boca Juniors and made his debut with a 9-minute substitute appearance in a 2–2 draw with São Paulo F.C. in the 2006 Recopa Sudamericana. On 31 August 2008, Metalist Kharkiv secured Maidana's transfer. Two years later, in January 2010, he was loaned to reigning Argentine champions Banfield.
After six months in Banfield, Maidana joined River Plate, rivals of his former team Boca Juniors. The defender scored River's winning goal in the 1–0 victory over Boca for the 2010 Apertura's Superclásico.
