'Sun': Ibrahimovic set to return to Man Utd training next week

This comes after the 36-year-old posted a video on his Instagram which showed him working on his fitness on an exercise bike in an oxygen tent with a trainer under the caption "high altitude work".

Ibrahimovic is attempting to regain peak fitness after picking up a knock to his knee in the Manchester club's fixture against Burnley on Boxing Day. 

The setback followed a lengthy spell on the sidelines due to a knee ligament injury which ended his impressive debut campaign under Jose Mourinho prematurely. 

Thankfully, the Swede will be allowed extra time to return to training, if he needs it, with United's attacking options being boosted by the signing of Alexis Sanchez. 

In his first year in England, Ibrahimovic scored 28 goals in 46 appearances in all competitions for the 'Red Devils' but has only managed to feature seven times this season, netting once.
