Zlatan Ibrahimovic's rapid return from knee surgery hasn't surprised anyone amongst the Manchester United medical staff.
The Swede is now close to being offered a new contract at United.
"They had never seen anything like it when Zlatan signed," a source told the Daily Mail.
"Players who come in undergo a number of tests so we can figure out what kind of shape they are in, what their training regime should look like and what diet will work best. Some players will come in and they will be the best we have seen in a certain category.
"Speed, for example. Zlatan came in and set multiple records across a variety of tests. Superhuman was the word some were using."
