Zlatan Ibrahimovic knee joint is apparently "so strong" that his surgeons have asked to use the Manchester United striker for medical research purposes. The 35-year-old went under the knife last week after suffering a cruciate ligament injury during United's 2-1 Europa League win over Anderlecht in mid-April. The injury may have prematurely ended Ibrahimovic's season but it could well end up benefiting the rest of humankind if the University of Pittsburgh School of Medicine can unlock the secrets of his pristine physical condition. Speaking to Swedish paper Expressen, the player's agent, Mino Raiola, said: His knee is so strong that the doctors said they had never seen anything like it. He has a knee that it is almost impossible for a football player with a 20-year career to have. It was quite clean, there was no harm in it. Zlatan is so strong that the doctor wants him back after his career to research on him. They work on the world's best research institutions for the knees and
zlatan is the benjamin button of football.
