The ex-Manchester United striker, who is widely expected to re-sign with the club when he is fully fit and ready to play towards the end of the calendar year, saw his 2016/17 season end early when he damaged ligaments in his left knee in a Europa League clash with Anderlecht.
It was initially feared that Zlatan's illustrious career could be over there and then, but he underwent successful surgery at a Pittsburgh hospital in early May and a return to playing was soon on his radar.
On crutches at the Europa League final at the end of May, the 35-year-old was pictured walking freely in Manchester city centre with Mino Raiola recently. And in his latest Instagram post, Ibrahimovic has shared a video of himself in the gym doing leg exercises.
Captioned, 'Power is nothing without control', the clip shows that his left knee appears to be just as strong as his right and is sure to get United fans excited.
At the end, the camera turns to a friend who says, 'The king of football is coming back'.
Ibrahimovic apparently refused the offer of a contract extension from United beyond his initial 12 month deal, unwilling to accept wages while unable to repay the club on the pitch. But he has been doing his rehab work at Carrington since returning from America.
Jose Mourinho has also hinted a new deal is possible and has been talking about Ibrahimovic as if he is still very part of the plans - the boss has referred to United's four injuries on more than one occasion in recent days, including Zlatan with Marcos Rojo, Luke Shaw and Ashley Young.
