Zlatan Ibrahimovic's injury-enforced absence means he has more time to ape around.
The former Sweden captain is without a club at present after suffering knee ligament damage in Manchester United's Europa League tie with Anderlecht in April.

United boss Jose Mourinho has hinted Ibrahimovic will be offered a new deal when he proves his fitness but, in the meantime, the shy and retiring 35-year-old was happy to show his rehabilitation was going well by showing off his impressive torso and comparing it to fictional movie character King Kong.
