Zlatan Ibrahimovic has backed himself to be a better player when he makes his Manchester United comeback.

Ibrahimovic has not played since April but is expected back from a knee injury before the end of the year.

And despite turning 36 last month, the striker is confident he can rediscover the form that saw him score 28 goals for United last season.

"The first thing I said to myself was giving up is not an alternative. I have come this far and I will finish on my terms, not anyone else's," he said in a promotional video for Volvo.

"I will stop when I want, in the way I want. Since then I have been in rehab training. I'm determined to return better and stronger than before. That is my goal and it will happen. There are no other options."

With Ibrahimovic still recovering in the summer, United signed Romelu Lukaku as a replacement. Lukaku has taken the No. 9 shirt while Ibrahimovic will wear No. 10 when he returns.

And the former Sweden international hinted that No. 10 might also be his position in Jose Mourinho's team after leading the line last season.

He added: "To me, No. 10 is the star. The one who makes the difference, gets noticed, wins the matches and is the leader. And I see myself in that position. But it is not something that is given to you, it is just something you are, that's just the way it is.

"To be honest, it is like a trigger for me coming back from that injury. Because I wore the No. 10 on the Swedish national team and PSG. I would have worn it at Inter [Milan] but I soon moved to Barcelona.

"I wanted it in Milan but took another number out of respect. In Ajax I didn't have it. I feel like a 10 and I stand for No. 10. It will go down in history that I always had No. 10."
