Early career Born in
Córdoba, Bergessio started his career in the lower leagues with
Club Atlético Platense. In 2005, he was signed by
Instituto Atlético Central Córdoba of the
Primera División, but at the end of
the season Instituto were relegated, and the player was sold to
Racing Club de Avellaneda. Bergessio contributed six goals in the
Apertura 2006 and, in the following year's
Clausura, continued to score on a regular basis. His pace and workrate made him a fan favourite at the
Estadio Juan Domingo Perón, and he notably netted against
Boca Juniors and
Club Atlético River Plate in the tournament.
Benfica, return to Argentina On 26 June 2007, Bergessio signed a five-year deal with
Primeira Liga club
S.L. Benfica for a reported
€2.5 million fee, as an unknown party remained eligible to 50% of the future transfer fee the Portuguese received. He only appeared in three league matches during his spell, one more than his
opportunities in the
UEFA Champions League, and returned to his country in January of the following year. In January 2008, Bergessio joined
San Lorenzo de Almagro. On 8 May, he was involved in the
Copa Libertadores tie against River where, after his team had two players
sent off and were 2–0 down, he scored twice to give it an improbable
aggregate win.
Saint-Étienne On 25 August 2009, Bergessio returned to Europe by agreeing to a four-year contract with France's
AS Saint-Étienne, for an undisclosed fee. He scored his first goal in his second appearance, a 1–1
Ligue 1 home draw with
AJ Auxerre, but netted just four times more in his one-and-a-half-season stint.
Catania In the last hours of the 2011 winter
transfer window, Bergessio joined Italian side
Calcio Catania, arriving on loan for the remainder of
the season – the
Sicilians had the option to sign him player permanently at the conclusion of this loan agreement. He made his
Serie A debut on 20 February, playing the full 90 minutes and being
booked in a 1–0 away loss to
SSC Napoli. After an initial delay in the transfer, Bergessio signed a permanent four-year contract on 29 August 2011 for €945,000. In the
2012–13 campaign, he became a key part of
Rolando Maran's team, forming an efficient attacking partnership with countrymen
Pablo Barrientos,
Lucas Castro and
Papu Gómez; he scored his first
hat-trick in Italy's top flight on 5 May 2013, in the 3–0 home win over
AC Siena. Bergessio helped Catania eventually finish in eighth position, with a record in total points for the fifth consecutive season. On a personal level he was also the club's highest scorer during a single campaign, since
Gionatha Spinesi netted 17 times in
2006–07. On 30 October 2013, Bergessio suffered a broken
fibula as a result of a late tackle by
Giorgio Chiellini in a 4–0 defeat at
Juventus FC.
Sampdoria On 1 August 2014, Bergessio was sold to
UC Sampdoria of the same country and league for a fee of €2.65 million, putting pen to paper to a three-year deal. On 3 June of the following year, after 24 appearances in all competitions and two goals, he was released by mutual consent.
Later years Bergessio moved teams and countries again on 24 June 2015, joining
Atlas F.C. from Mexico. The following 8 September, he signed a one-year deal with former club San Lorenzo. ==International career==
