Despite reaching the latter stages of his career at the age of 35, Ibrahimovic has scored 26 goals in all competitions this season including the winning goal in the EFL Cup final against Southampton two weeks ago.
Ibrahimovic only signed a one-year deal when he joined United but contract talks have stalled in recent weeks and Liverpool legend Robbie Fowler believes there could be another reason why Ibrahimovic is yet to commit another year to Jose Mourinho's side.
"I won't be surprised if Zlatan Ibrahimovic goes to China in the summer…but before he does, every member of the strikers club should thank him," Fowler told the Mirror.

"What he has done this season is remarkable. He’s not only proved forwards don’t have to retire at 30 – as seems to be the depressing modern trend – but he’s also encouraged Jose Mourinho to go against the new coaching orthodoxy.
"It’s become a mantra that every coach must follow: strikers have to be the first line of defence, they must put in miles of running to close down, to press, to turn over possession."
Fowler went on to say that he can see both Wayne Rooney AND Ibrahimovic leaving United this summer.

"How vital is it United keep him next season? Actually, not that vital," Fowler added.
"They are a massive club. Like the Liverpool's and Arsenal's of the football world, they should be able to attract the very best players in the world, every year.
"People have said it would be great to keep him so that the young strikers at the club can learn from him next season.
"But c’mon. At a club like that, you’re always there because you’re the best, because there is no one better. End of.
"So if he is at the same level next season, he should stay, and given his relationship with Mourinho I think he still could. But I wouldn’t bank on it. I can see him going off to China – maybe with Wayne Rooney – and United buying another top class striker.
"But if he does, then he’ll still have done every Premier League striker a massive favour."
