The 26-year-old is currently on international duty in the World Cup and has played in Argentina’s two games so far, their wins over Bosnia and Herzegovina (2-1) and Iran (1-0).
Di Maria, who has been linked with Manchester United and Manchester City, insists he is focusing on his country’s attempts to win their third world title but admits he does not know whether he will be at the Bernabeu next season.
Di Maria said: "I've asked my agent not to tell me anything about the talks he's having.
"I don't know what's going to happen with my career. I don't want to know anything about my future right now.
"I'm focusing on my national team and not on what's going on elsewhere,” he added.
"My team-mates and I don't read or listen to all the things being said in the media.
"We're just thinking about ourselves and the unity of the group."
Argentina struggled to a win over their Iranian counterparts, who seemed content to play a defensive game, and Di Maria has reacted angrily to suggestions that his side played below-par on Saturday.
He told reporters: "I don't know why you keep saying we weren't playing well. When a team has 11 players in penalty area it's impossible to get in there."
