The 36-year-old, who was recruited by the Major League Soccer outfit last week, has confessed that the switch could have happened in 2016.
"[The move] was supposed to happen before Manchester United. My head was here. I wanted to come here," Ibrahimovic told reporters in his first Galaxy press conference.
"Things go like they are not supposed to go, but the destiny said I will come here. Los Angles called and I answered."
Ibrahimovic, who scored 29 goals in 53 appearances for United, joined the MLS side after his contract at Old Trafford was terminated by mutual consent.
