Lingard would have his medical in Manchester before traveling to London to complete the move which could see him feature during the weekend if the deal is completed and registered by midday on Friday.
Lingard has failed to make a Premier League appearance this season which goes to show how low he has fallen in the pecking order which prompted him to be on the lookout in a bid to get more first-team minutes.
Newcastle and West Brom are understood to have approached Lingard’s representatives about taking the out-of-favour England international on loan, but the 28-year-old rejected their offers.
The total cost of a potential deal is thought to be more than £3m, taking into account the loan fee and Lingard’s wages.
United triggered a one-year extension on Lingard’s contract, which now runs until the summer of 2022, to protect his value ahead of a potential transfer.
United manager Ole Gunnar Solskjaer, had reportedly been reluctant to let Lingard go this month as a potential, unpredictable schedule is about to kick off amid the coronavirus pandemic.
However, Lingard is said to have personally argued his case to be allowed to go elsewhere.
The Norwegian was asked about Lingard – and Brandon Williams, who is attracting interest from Southampton and Newcastle over a potential loan move this month – this week and left the door open to a potential exit.
Solskjaer said: “They’re still part of the club, part of the squad, training well. No deal has been struck for any of the players yet going out – still a little period left, of course.
“There’s been many clubs interested in our players, so let’s see what happens.
“For me, it’s also important to take our wishes and our plans into consideration but also the players of course, because they are Man Utd people and players through and through.”
