Carlos Ayrton Cougo Rivero (born 15 June 1996) is a Uruguayan footballer who plays as left back for Brazilian club Sarmiento, on loan from Liverpool Montevideo.
Club career
Cougo was born in Melo, and joined Defensor Sporting's youth setup at the age of 15. He made his first team debut on 14 February 2016, starting in a 1–3 home loss against Racing Montevideo.
Cougo subsequently became a regular starter, and signed for Paraguayan club Libertad on 2 January 2019, after the club bought 50% of his economic rights for a US$ 1.5 million fee. On 31 December, however, he returned to his home country after agreeing to a one-year loan deal with Nacional.
Back to Libertad for the 2021 season, Cougo again failed to establish himself as a starter, and was loaned to Campeonato Brasileiro Série A side Avaí on 21 January 2022.
