The full back became the first arrival of the David Moyes era last summer, arriving at the club for a reported fee of £1m from Penarol having previously made a number of trips to the club and impressed the coaching staff.

He was a regular at right back for Warren Joyce's Under-21 side last term and had been tipped to provide back up for Rafael da Silva in the first team this season.

Varela becomes the seventh player to have left United on transfer deadline day. Having failed to win over van Gaal, Hernandez was allowed to join Real Madrid on a season-long loan with the option of a permanent deal, while the arrival of Radamel Falcao from Monaco saw the club sanction Danny Welbeck's move to Arsenal for a reported fee of £16m.

Promising academy product Tom Lawrence joined Leicester City on a permanent deal where he was later joined by Nick Powell who arrived at the King Power Stadium on loan.

Michael Keane also left the club to join Burnley in a late deal on loan while Tom Cleverley's protracted move to Aston Villa was ratified by the Premier League on Tuesday.

Amid the spate of late departures, United have also confirmed they agreed a deal to sign Timothy Fosu-Mensah from Ajax before Monday's transfer deadline.

A statement from the club read: "The 16-year-old is a powerful defender who caught the eye at the AEGON Future Cup and is highly regarded in his homeland.

"Fosu-Mensah still requires an International Transfer Certificate to be processed in order to make his debut for Paul McGuinness' Academy squad, but his versatility and ability mark him out as an excellent addition for the Reds."
