The defender was away along with fellow Manchester United summer signing Angel Di Maria, who helped Argentina thrash Hong Kong 7-0 in Tuesday night’s friendly.
Rojo was an unused substitute as Ever Banega opened the scoring before Gonzalo Higuain, Nicolas Gaitan and Lionel Messi all bagged braces in the rout.
Rojo looks pleased to be back in Britain however, as he posted the picture above on Instagram and wrote: “I’m already happy at home with my love.”
The denfender has made four Premier League appearances since his £16m switch to the Red Devils from Sporting Lisbon in the summer transfer window.
Meanwhile, Di Maria, who moved to United in a club-record £59.7m deal in August, has scored three goals and made three assists in five top-flight games.
