The Argentina international has been afforded an extended break by manager Louis van Gaal after the centre-half helped his country reach the Copa America final before a penalty shootout loss to Chile.
The Red Devils are currently preparing to face Champions League winners Barcelona on Saturday night after United eased to victories over Club America and San Jose Earthquakes in the opening game of their pre-season tour of United States.

The Argentina defender endured an injury-hit first season at Old Trafford following his big-money move last summer.
The World Cup finalist has made 21 Premier League appearances for the Red Devils this term, racking up just over 1,700 top-flight minutes.
Rojo moved to United in a £16m deal from Sporting Lisbon after an impressive World Cup campaign in Brazil.
