The Swede, who has scored 28 goals for United this season, badly injured his knee last month and is expected to be out for an extended period of time.
Ever the eternal optimist, when he was asked how long it will be until he is back training, Ibrahimovic told Sky Sports Italia: "I work hard. I'll be back in a few weeks,"
Ibrahimovic was then asked if he knew where he will play next season, to which he replied: "We'll have to see. Good question!"
