The Swedish superstar and Portuguese tactician have reunited at Old Trafford with success thus far and the striker puts it down to a strong bond that was first created at Inter Milan back in 2008.
Ahead of the weekend's derby with Manchester City, Ibrahimovic touched on the working partnership he has with Mourinho, who he has labelled simply as a 'winner'.
"For me a relationship between a player and a coach has to be between a player and a coach," he said.
"I know this coach from before, I know what he wants. I know his demands, I know what he goes for.
"In a short time he was very successful and not every coach has that. You have coaches that build up and clubs have a lot of patience with them.
"Wherever he went he won. When he was in Porto, for example, he won the Champions League when nobody expected him to.
"And he does what he needs to do to win. And he'll make sure he wins, just like me as a player.
"I don't accept to lose, because when I lose I learn. And I will not lose, I will win."
Zlatan added: "He's a winner, I see myself as a winner also. I like to win, I'll do anything to win. He thinks the same thing. He won. And I won.
"We won when we were young and we will win when we are a little bit older."
