AC Milan striker Zlatan Ibrahimovic admits he's unsure what retirement will bring.

The 40 year-old knows the time is coming to soon hang up the boots.

“I do feel a slight sense of panic at the prospect of retirement," confessed Ibra in his press conference.

“I will certainly keep playing for as long as possible, as long as I can get results and am not suffering. I want to end my career without regrets, so I have to maximise my time.

“I don't know, we'll see when the day comes. I could start straight from when I retire, or take a break, or disappear completely.

“I know the adrenaline I feel at the moment will never be the same. We are programmed to wake up, go to training, return home and rest. This goes on for 20-25 years, but one day I will wake up and have nothing planned, and that will be a strange feeling."
