Nani made his feelings clear, but the former Bayern Munich midfielder gave the perfect response by curling in his first goal for the club.
Speaking about the free-kick confrontation, Hargreaves said: "He didn't seem too pleased. He protected the ball at first. He didn't want me to have it. I just took it because I felt I could score.
"He said that if I hadn't scored, then he would have been a bit upset with me, so I'm glad it went in."
