The Argentine wants to represent his country, but knows he will not be able to force his way back into the national team if he is not playing for his club.
The 29-year-old, has only made 63 Premier League starts for Man Utd since he joined in a £16million deal from Sporting Lisbon in 2014.
He was left out of Argentina’s 2019 Copa America squad – who reached the semi-finals – due to a lack of game time.
After a decent pre-season at Old Trafford, Rojo has been told by Argentina boss Lionel Scaloni that he could be part of his plans – if he plays.
He said: “I talked to Scaloni, he told me that he was happy because in the pre-season I had played many games, that I looked good and that was why he called me, but that I had to play.
“I am sure that to play in the national team you have to play in your club, you have to be always, and when you are here show why.”
Rojo has not featured for United so far this season and he will be looking for a move away in January if more minutes don’t materialise, reports The Sun.
Rojo said: “I had the possibility of Everton, but by decisions of the club or the technician could not be done.
“Now I have to fight it until December and if it does not touch me, I will try to leave.
The World Cup qualifiers and the Copa America are coming I want to be part of that.
“I do not want to be out again, I want to exhaust all the possibilities and compete for to be here.
“I feel very well physically. The most important thing for me is that, it is the coach’s decision to play or not.”
