The 35-year-old is currently without a club after the Red Devils opted against triggering an extension to the striker's one-year deal due to injury.
The former Sweden international suffered cruciate ligament damage towards the end of last season, but manager Jose Mourinho recently confirmed that talks have begun over a possible deal that would welcome the forward back into the fold from January.
According to The Independent, during those discussions, the opportunity of a coaching role for when Ibrahimovic decides to hang up his boots has been mentioned.
Mourinho reportedly believes that the former Barcelona star would be an important go-between for players and the management, while also being able to offer his experience and knowledge.
Ibrahimovic scored 28 goals in 46 appearances in all competitions last season.
