Jose Mourinho has told midfielder Paul Pogba to curb his off-field commitments and instead focus on his Manchester United career, according to a report.
The France international is currently nursing a hamstring strain picked up in the Europa League win against Rostov earlier this month, which he has failed to recover from over the international break.
It is claimed by The Mirror that Mourinho was unhappy with the record signing's Twitter emoji stunt earlier this season - part of many commercial agreements in place to appease his numerous sponsors.
Pogba is said to have been told to cut down on his activities away from the field, or else he is at risk of being dropped from the side once returning from injury.
United spent £89m to bring their former youth-team product back from Juventus last summer, but he has largely come under fire for some underwhelming displays.
