The 35-year-old suffered a cruciate knee-ligament injury against Anderlecht in April, and underwent surgery in Pittsburgh earlier this week.
Ibrahimovic was operated on by renowned sports doctors Freddie Fu and Volker Musahl, who were said to be utterly astonished by the strength and condition of the striker’s knees and keen to take another look at them when he eventually retires from playing.

‘His knees are so strong that doctors said they had never seen anything like it,’ Ibrahimovic’s agent, Mino Raiola, is quoted in Swedish newspaper Expressen.
‘He has a knee that’s almost impossible for a football player with a 20 year long career to have. It was perfectly clean, there were no damage to it.

‘Zlatan’s knee is so strong that the doctor’s want him to return after his career to do research on him. They work at the world’s best research institute for knees and ligaments.
‘They research a lot about the subject and that is why they are better than everyone else. So after Zlatan’s career we will go back and open him again to research his ligament.’
Ibrahimovic – who looks unlikely to play again for Man United after netting 28 times in his first season at the club – will remain in Pittsburgh for his rehabilitation under the watchful eyes of doctors Fu and Musahl.
