* Senior club appearances and goals counted for the domestic league only and correct as of 7 June 2015.
Born in La Plata, Buenos Aires Province, Saja had nearly 200 overall appearances for San Lorenzo de Almagro, being voted South America's best goalkeeper in 2002. In 2001 he helped the team win the Clausura and the Copa Mercosur, adding the following year's Copa Sudamericana.
Saja split the 2003–04 season with Brescia Calcio and Rayo Vallecano, being first-choice and dropping down a level with the latter. Moving to another club in Spain and in the second division for the following campaign, he would also be relegated with Córdoba CF.
After a brief spell in Mexico with Club América, Saja returned to San Lorenzo for 2005–06: he made 33 appearances and scored five goals in the Primera División, but was eventually sent out on loan for the fifth time, this time to Grêmio Foot-Ball Porto Alegrense after falling out of favour with new manager Ramón Díaz.
Released in 2008 Saja signed a three-year contract with AEK Athens FC, earning approximately €400.000. He appeared in 29 games in his first year to help his team finish fourth in the Superleague, but it was also quickly eliminated from UEFA Cup contention.
Return to Argentina
On 29 June 2011, Saja and AEK agreed to terminate his contract one year before it expired. Shortly after, the 32-year-old returned to his homeland and joined Racing Club de Avellaneda, netting his first goal for his new team on 29 September of the following year, through a penalty against former club San Lorenzo in a 4–0 win; he was also the goalkeeper with the least goals conceded in the 2011 Apertura, breaking a club record for a short tournament held by Carlos Roa since 1992.
On 10 June 2013, again from the penalty spot, Saja scored against Boca Juniors (2–0 home triumph).
