The France international enjoyed a sensational start to the season after being unleashed by Nemanja Matic's arrival at Old Trafford from Chelsea.
But he's not played since September 12 after limping out of United's 3-0 win over Champions League group stage opponents Basel.
Jose Mourinho revealed his fears that the hamstring injury Pogba had picked up would keep him out for the long-term.
And although he's a certainty to miss Saturday's showdown with arch-rivals Liverpool, it seems the 24-year-old could be back in action sooner than first anticipated.
The Sun have pictures Pogba can be seen going through an intense workout in the baking Miami heat.
The midfielder is shown to be running, skipping, jumping and doing press-ups under the watch of personal trainers - all actions that suggest he's on the mend.
United have six fixtures before the end of October as they take on Liverpool, Benfica twice, Huddersfield, Swansea and Tottenham.
And Pogba may be hoping he can return before that hectic run of games is over.
United visit fellow title-chasers Chelsea on November 5, a match Mourinho is certain to want him back for.
In the meantime, United can go top of the Premier League this weekend providing they beat Liverpool (12.30pm) and outscore early leaders Manchester City by at least two goals.
