The Swedish international, who has previously spoken of his determination to win a league title with United, has said that he “never leaves a job unfinished”.
Ibrahimovic has enjoyed a fine debut season at Old Trafford and is currently United’s top goal-scorer in the league this season, with 15 goals.
He also scored a brace as the United beat Southampton 3-2 in the EFL Cup final, prompting manager Jose Mourinho to urge the forward to stay on at the club.
The 35-year-old’s apparent indecision over whether to extend his £250k-a-week into another year at Old Trafford led to rumours he was considering one final, lucrative transfer to the MLS.
But Ibrahimovic appeared to quash such speculation when he reiterated how much he is enjoying his time in Manchester.
“I have an option for another year, I want to do great as long as I’m here, so let us see, there is a lot of time,” Ibrahimovic told the Manchester Evening News.
Speaking about his time at United so far, the forward added: “I’m enjoying it. I am a person when I go into something I put my head 200 per cent, and I do what I’m good at.
“I go in, I go for the kill and I go out. And when I go out there is no complaints, that’s what I do. I never leave a job unfinished.”
The 35-year-old has scored 26 goals in 41 appearances, the highest tally by a player for the club in four years.
Ibrahimovic praised United and Mourinho, saying: "I'm enjoying being at a fantastic club, without doubts, one of the biggest clubs in the world with a great coach. I know him before, he's a winner, he's the perfect coach for this club.
"Being a Manchester United player, I don't know how many people have that possibility but I am a Man United player, people wanted me here. I chose the best English club."
