The first trophy of Guido Marcelo Carrillo's career came in May 2017, when AS Monaco were crowned champions of Ligue 1 in 2016-17. By then the striker, born on 25 May 1991 and raised in Magdalena, in Buenos Aires Province, had already come through the youth ranks and spent his first professional years at Estudiantes de La Plata. He went on to play for Southampton, Leganés, Elche and China's Henan Songshan Longmen before returning in January 2023 to the club where he made his debut, winning five trophies with them between 2023 and 2025.
Youth career and debut at Estudiantes
Carrillo came through the Estudiantes academy. In April 2007 he played for Argentina's under-18 side in a friendly against the United States that ended 5-0, coming on in the second half and scoring. His first-division debut came on 21 May 2011, in the Torneo Clausura against Huracán, when he came on in the 79th minute wearing the number 17. From there he gradually established himself as the La Plata side's centre-forward. Between 2011 and 2015 he made 118 league appearances for Estudiantes and scored 28 goals, numbers that drew interest from European clubs.
The move to Europe with Monaco
In July 2015 Estudiantes accepted an offer from AS Monaco reported at around 10 million US dollars. On 22 July that year, in a friendly against Mainz, he opened his account for the club with a header. He spent two and a half seasons in the principality, making 65 Ligue 1 appearances and scoring 15 goals. He was part of the squad that won the 2016-17 French title, the first trophy of his professional career.
Southampton and two loan spells at Leganés
In January 2018 he joined Southampton for a fee the BBC put at around £19 million, on a three-and-a-half-year contract. He struggled for regular football in the Premier League, playing seven matches without scoring. In July 2018 the English club loaned him to CD Leganés, where he was a starter in 2018-19, with six goals in 33 competitive games. In September 2019 he returned to Butarque on a second loan, which ended in the summer of 2020 with the Madrid-area club's relegation. Across both spells he made 56 LaLiga appearances and scored seven goals.
Elche and a spell in China
In October 2020 he terminated his Southampton contract and signed as a free agent for Elche, newly promoted to the Spanish top flight. He spent two seasons there, until June 2022, with five goals in 50 league games. In August 2022 he moved to the Chinese Super League to join Henan Songshan Longmen, again on a free transfer. He played 13 matches and scored twice there before heading back to Argentina.
Return to La Plata and the 2023 Copa Argentina
His return to Estudiantes was made official on 10 January 2023. The first trophy of his second spell followed that same year: on 13 December 2023, at the Estadio Ciudad de Lanús, he scored early in the second half to settle the Copa Argentina final against Defensa y Justicia (1-0). It was the club's first Copa Argentina, and the win also earned Estudiantes a place in the 2024 Copa Libertadores.
The 2024 and 2025 titles
In May 2024 he started the final that gave Estudiantes the Copa de la Liga Profesional. On 21 December that year, in Santiago del Estero, his header completed a 3-0 win over Vélez Sarsfield in the Trofeo de Campeones. A year later he scored in another final. On 13 December 2025, again in Santiago del Estero, Racing led the 2025 Torneo Clausura final 1-0 through Adrián Martínez until Carrillo, in stoppage time, headed in a José Sosa set piece to force a penalty shootout, which Estudiantes won 5-4. On 20 December 2025 the side beat Platense 2-1 in San Nicolás to lift the 2025 Trofeo de Campeones, Carrillo's fifth trophy since rejoining the club in 2023.
