The striker is currently out of contract following his release this summer from United.
The 35-year-old's serious knee injury sustained in April saw Manchester United not take up the option to extend his deal.
However, Ibrahimovic is quickly working his way back to fitness.
As a result, Jose Mourinho has revealed the club are in talks about a comeback later in the season.
And according to The Sun, Ibrahimovic is expected back at Carrington as early as tomorrow.
American surgeons ordered the Swede last week to take it easy as he looks to rush back from injury.
But he is pushing hard with a comeback happening shortly.
Ibrahimovic has been carrying out his rehab with United ahead of a new deal which will apparently be penned within the next few months.
A United source told The Sun: “Zlatan will be coming back to resume his rehab from his knee operation very shortly.
“He’s been told to calm it down a bit, but that’s just not what he’s like, he’s so determined.
“Everyone is delighted with his progress, but want him to strike the right balance between rehab and recovery.
“He’s sure to come back to the club on a contract, and they want him fit and raring to go.”
Ibrahimovic's replacement up front Romelu Lukaku netted twice for United in the 4-0 win over West Ham in Sunday's Premier League opener.
But Mourinho would welcome the experienced hitman back with a January return possible.
