Somoza began his professional career playing for Vélez Sársfield in the Argentine Primera in 2001. He played for the club for five years, and was a key player in the 2005 Clausura tournament winning team.
In 2006, Somoza was transferred to La Liga's club Villareal CF on a five-year contract. At Villarreal he joined fellow countrymen Juan Román Riquelme, Gonzalo Rodríguez, Rodolfo Arruabarrena, Fabricio Fuentes and Mariano Barbosa. However, he spent only one season in Villarreal, being loaned in August 2007 to Real Betis. The Argentine midfielder was presented to the media on 14 August and made his first appearance in a friendly against Real Zaragoza two days later. His first competitive debut came in the season against Recreativo Huelva, on 26 August.
After his second season in Spain, Somoza returned to Argentina for the 2008–09 season to play again for Vélez Sársfield. During the 2009 Clausura, he was part of the squad that won the Argentine league championship, but did not participate in any of the games due to an injury he had suffered at the end of the previous tournament.
In 2015, Somoza agreed on a free transfer to Vélez Sarsfield, his third spell with the club.
Somoza debuted for Argentina by then new manager Alfio Basile in the friendly international against Brazil at the Emirates Stadium in London, England during 2006. Two years later, while playing for Vélez, he was called again by Basile for the match against Chile, although he remained on the bench.
After four years, the midfielder rejoined the national team upon Alejandro Sabella's call up to play the Superclásico de las Américas. Sabella also called Somoza for the FIFA World Cup qualifying games against Peru and Uruguay in 2013.
