"I am super excited. I know what I come with. I know what I am able to do," he said to Calen Carr, a former MLS player.
"This is just a new adventure for me - a new challenge. I am looking forward to conquer the US just like I conquered Europe. I'm pumped!
"After 20 years in Europe playing for the best clubs in the world with the best players in the world, I have been winning so much.
"It is time to move to a different continent and try the MLS. For me, there was no question about it - Galaxy was the team and I chose them. They didn't need to choose me."
He went on to speak about the glowing reviews that the MLS has had from other players who made the switch, including David Beckham.
"I met David when I played at PSG and he talked a lot about Galaxy and the experience he had in America. He was all positive and said 'you should go over and try it out'," Ibrahimovic added.
"He said everything is fantastic, in progress but to be part of it is amazing and something he was proud of. These words make it easier when you have to choose your next step."
Ibrahimovic could potentially make his debut in the new LA Derby, against expansion team LAFC - new to the league this year.
"I think it will be the biggest match during the season, because it is a new team against a big team from the same city. The competition, the rivalry will be there because when two teams come from the same city, one wants to be better than the other one obviously.
"But I am not worried about this because these games I was born for."
