Guido Mainero (born 23 March 1995) is an Argentine professional footballer who plays as a winger for Instituto.[2]
Mainero joined Instituto's academy in 2002.[3] He was moved into their first-team for the 2014 Primera B Nacional campaign.[2] [4] He made his professional debut on 5 November 2014 during a win over Boca Unidos, which was the first of thirty-two appearances in his opening three seasons.[2] [5] In his fourth, he netted four goals throughout the year; notably the first against Villa Dálmine in April 2017.[2] In January 2018, Mainero completed a transfer to Argentine Primera División side Vélez Sarsfield.[2] [6] His first appearance in the top-flight came in a 2–0 defeat to Chacarita Juniors on 5 February.[2]
In July 2019, Mainero completed a season-long loan move to Defensa y Justicia.[7] He made twelve appearances in all competitions whilst scoring two goals; in the league versus Talleres and Rosario Central.[2] His 100th career appearance arrived on 3 March 2020 in the Copa Libertadores versus Santos; in what was his last match for Defensa due to the COVID-19 pandemic.[2] He featured for Vélez on 31 October versus Huracán, before departing on loan in November to Chilean team Deportes Iquique.[2] After debuting against Cobresal on 23 November, Mainero scored on 8 December versus Unión Española.[2] After returning from loan in June 2021, he was loaned out once again, this time to Sarmiento until the end of 2022.[8]
