Somma, who was born in Latina, Lazio, started his career with Genoa and then spent his later years mostly at the Serie C1 and Serie C2 level, playing for several Campanian teams. He retired in 1997.
Coach
Somma started his coaching career in 1997 with amateur team Pro Cisterna, and then served as head coach for several other Serie D teams, including Potenza and Cavese, winning promotion to Serie C2 with the latter. In 2003, he was appointed at the helm of Serie C1 team Arezzo, leading the Tuscan side to a historical triumph in the league. This caused interest by Empoli, which chose to offer him the job for their 2004–05 Serie B campaign. As Somma managed to win a personal third consecutive promotion, leading Empoli to become Serie B runners-up, he was confirmed by the Tuscans for their 2005–06 campaign; despite an impressive start, Empoli's performances slowly fell down, causing Somma to be dismissed from his job on January 2006. Somma started the 2006–07 season as head coach of Brescia in the Serie B, with the aim to lead the rondinelle back to the top flight: however he was sacked on February 2007 as he did not manage to obtain more than a mid-table place. On October 2007 he was appointed at the helm of Piacenza to replace Gian Marco Remondina. He led the biancorossi to escape relegation in the season, but was sacked immediately after the final matchday. On February 2009 he was appointed to replace Alessandro Costacurta as head coach of Serie B club Mantova. He left at the end of the season after having guided his side to a mid-table finish. On October 2009 he returned into footballmanagement as new head coach of Triestina, replacing dismissed boss Luca Gotti. However, he was sacked on February 2010, with Triestina in 18th place, and only one point shy of immediate relegation. On 1 October 2012 he was named new coach of Grosseto en place of the sacked Francesco Moriero., but on 18 November 2012 he was also sacked. On 8 June 2014 he was named new head coach of Lega Pro club Salernitana. He was however dismissed as head coach only two months later, on 17 August 2014, after only one game in charge of the team.
