The Manchester United star says that he wishes he had the mind he has now as a younger player, which would have made him "even more phenomenal".
"I think I play much more intelligently now because, of course, you change a lot during the years," the Swede said.
"You get a different physique, you get a different condition, strengths and experiences. But I wish I had the mind that I have today 10 years ago, because then I will be even more phenomenal".
The former PSG and Barcelona striker also said that that he's trying to help young striker Marcus Rashford, who is at the other end of his career.
"I try to help in every way I can with my experience and the goals will come," Ibrahimovic said. "Goals are extra, a bonus lets say. If I score then I help the team, but I think I can help in many ways and this is the experience thing.
"Marcus is a young player, his career has just begun and I am towards the end of my career.
"I try to help in many ways without the ball, with the ball, with movements, by communicating, by sacrificing. It is part of the game and as a player I want to be as complete as possible, so this is one of the things I have been trying to do".
