United have resigned the legendary Swede on a one-year contract following his stunning campaign at Old Trafford last term.
The 35-year-old striker scored 28 goals for the Red Devils before a nasty knee injury cut his season short.
Ibrahimovic believes he has unfinished business at United and Thierry Henry has backed him to be a star in the Premier League again this season.
Henry told Sky Sports: “Zlatan takes it as a challenge that he has with himself. I think he wants to do more, and he still didn’t win the league.
“I know that he wants to win the Premier League, to make England another country that he conquered.

“I’m not surprised, because if I was there [at Man Utd] I would want to keep a guy like Zlatan in and around the dressing room.
“Having him around [Romelu] Lukaku, having him around Marcus Rashford [is beneficial]. Rashford was talking about it last year, he knows how to get that dressing room together.
“I’m not surprised in a way because we are talking about Zlatan Ibrahimovic, one of the best that has done it in the game, for me.”
Ibrahimovic is still recovering from his injury but is expected to be back in action far earlier than first expected.
Henry is convinced that the all-star forward will hit the ground running once again when he returns for United.
He added: “First and foremost he already showed us that he can still perform.
“Yes, there may be a question mark with some people asking if he will return to what he was [before the injury], I have no doubt that he will.
“I know the man, and I know how he is going to work. He showed us with a couple of moves on social media, that his knee is alright. So I have no doubt with that.
“But what is important is to have a guy like that around the place. He knows what it takes to win.”
