Gustavo Iván Coleoni (born 16 August 1968) is an Argentine football manager and former player who played as a midfielder.

Coleoni is nicknamed Sapito (Little Frog) due to his small height and his jumps to avoid his opponents.^[1]

Born in Córdoba, Coleoni was a Talleres youth graduate. During his youth, due to his low height, the club paid a growth hormone treatment similar as to Lionel Messi's, but it never fully worked.^[2][3]

After only playing two friendlies in the first team, Coleoni resumed his career with Peru's San Agustín and Chile's Magallanes, aside from lower league sides in his native region.^[4]

After retiring Coleoni took up coaching in 1997, being initially a coordinator of his first club Talleres' youth sides and later being their manager. In 2003 he moved to Racing de Córdoba; initially a general coordinator, he was manager of the club's youth categories in 2004, and subsequently became their first team manager in 2006.^[5]

On 17 December 2006, Coleoni was named manager of Gimnasia y Esgrima de Mendoza,^[6] but was subsequently replaced by Ricardo Dillon. He was subsequently in charge of Juventud Antoniana also in the 2007 season, but resigned.

On 3 June 2008, Coleoni returned to Juventud Antoniana.^[7] He narrowly missed out promotion to Primera B Nacional in his two seasons in charge, and later moved to Juventud Unida Universitario in July 2010 as a general coordinator.

In September 2010, Coleoni was named at the helm of Central Norte.^[8] The following 21 February, he was named in charge of former side Talleres, with the club in the Torneo Argentino A.^[9]

In June 2011, Coleoni returned to Racing de Córdoba as first team manager.^[10] Roughly one year later, he was appointed at the helm of Santamarina,^[11] before returning to Central Norte in 2013.^[12]

In January 2015, after short periods in charge of Guillermo Brown^[13] and Sportivo Patria,^[14] Coleoni returned to Santamarina.^[15] He left the club in June 2016 to take over Ferro Carril Oeste in the second division.^[16]

Coleoni was sacked by Ferro on 15 December 2016,^[17] and took over Central Córdoba de Santiago del Estero the following January.^[18] Despite suffering relegation in his first season, the club won the 2017–18 Torneo Federal A and subsequently achieved promotion to the Primera División and reached the finals of the Copa Argentina in 2018–19.^[2]

On 17 March 2020, Coleoni resigned from the Ferroviarios.^[19] On 30 December, the club announced his return, effective as after the ending of the 2020 Copa de la Liga Profesional.^[20]
