We'd like to thank Marcos Rojo for his time at United and wish him the best of luck for the future! #MUFC— Manchester United (@ManUtd) February 2, 2021
United signed Rojo from Sporting Lisbon for a fee of £16m, after his strong showings with Argentina in the 2014 World Cup but he could never secure a first-team spot with United.
Despite signing a new contract in 2018, Rojo struggled to keep his place in the United side, and leaves having made 122 appearances across all competitions.
United appeared to have made something initially on the loan deal, but it now appears it was a free transfer.
Rojo has spent much time recently back in Argentina after he was loaned back to Estudiantes for the second half of last season.
“Marcos will return to his homeland on a permanent basis, after agreeing terms with the reigning Argentinian champions,” a United statement read.
“Everyone at the club would like to wish him all the best for the future.”
