Manchester United defender Marcos Rojo is set to join Estudiantes on loan, sources have told ESPN.
Rojo will move back to the Argentina side, whose chairman is former United midfielder Juan Sebastian Veron, until the end of the season as he looks for more regular first-team football.
The 29-year-old, who moved to Old Trafford from Sporting Lisbon for £16 million in 2014, has been restricted to just nine appearances this season and has not featured since the 3-0 win over Partizan Belgrade in November.
He has 18 months left on his contract, and the option of another year, after signing an extension in 2018.
Rojo won the last of his 63 senior caps for Argentina in an 4-0 international friendly win over Mexico last September. Argentina will co-host this summer's Copa America tournament alongside Colombia.
Meanwhile, sources have told ESPN that Timothy Fosu-Mensah will not be loaned out ahead of Friday's transfer deadline.
The Dutchman, 21, has not played this season because of injury but has returned to training and will stay to provide cover in defence and in midfield.
United are also close to signing Southend United goalkeeper Nathan Bishop. The 20-year-old, who has been capped at England youth level, has made 17 appearances for the League One club this season.
