Marcelo Sarmiento is an Argentine midfielder who was born in Cordoba, Argentina on November 3rd 1979. Sarmiento began his career with local outfit Talleres de Cordoba. After a few years of semi regular football he moved to Bulgaria to sign with Litex Lovech in 2002. Sarmiento failed to settle at Litex however, making just four appearances. He returned to Argentina in 2003 and established himself as a regular with Olimpo. Sarmiento spent the 2005/06 season with Argentinos Juniors.
On 8th June 2006 Sarmiento signed with English Championship side Southampton on a season long loan. Sarmiento made his debut on 23rd August 2006 as a substitute in a League Cup victory over Yeovil, and looked impressive. The Argentine made just three more appearances for Saints, all in cup matches. Sarmiento looked good on the rare occasions he was given a run out. His passing and technique were top draw, which was why it seemed somewhat unfair that he wasn't given more of a chance. Saints boss George Burley believed he lacked the physical qualities needed to compete. He returned to Argentinos Juniors after his loan spell at St Marys was terminated on 19th January 2007.
In June 2007 Sarmiento signed with Greek outfit Larissa, who were coached by former international star Giorgos Donis. The former Saints man was a key player for Larissa in his two seasons at the club, who he represented in Europe, coming up against Blackburn and Everton in the UEFA Cup. Sarmiento followed Donis to Atromitos in 2009. He made his debut for the club on 22nd August 2009 in a 1-0 loss at Aris. Sarmiento helped Atromitos reach the 2011 Greek Cup final, which they lost 3-0 to AEK.
In July 2011 Sarmiento returned to Argentina to sign for Union de Santa Fe
