Aubameyang is attracting interest this summer following an impressive season at the Emirates.
Arsenal fans are desperate to see the Premier League Golden Boot winner remain in north London beyond the summer.
But Unai Emery knows he must sell players to raise funds for his top transfer targets.
The Times report Aubameyang is one of the stars Arsenal are considering selling this summer.
However, they want to recoup the £56m they paid for the striker in January 2018.
Aubameyang turned 30 earlier this month meaning it is unlikely any clubs will want to splash out large amounts of money acquiring his signature.
United remain interested and may soon be flush with cash should Romelu Lukaku join Inter Milan before the end of the summer window.
Meanwhile, a number of Chinese sides continue to chase Aubameyang and may be more inclined to meet Arsenal’s hefty valuation.
Emery would certainly prefer to keep the Gabon international at the club in the coming months.
And the Spaniard has been told by talkSPORT host Adrian Durham to quit his post at Arsenal if a transfer does materialise.
“If Aubameyang, having scored all those goals for Arsenal, one of the few bright spots for Arsenal last season, if he went to Man United it would be right up there with the Van Persie thing as a betrayal of the Arsenal fans,” Durham said.
“I think Arsenal fans would look at this and say ‘Hang on a minute we haven’t been forking out money following this club, putting up with mediocrity by their standards for all these years just for us to get a decent strike partnership going and then one of them gets flogged’, to a rival as well.
“I think this deal cannot happen, I think Emery needs to come out and say ‘Right this deal cannot happen and if it does happen, I’m walking out on the club’.
“Something has got to happen to stop the bad decision-making at Arsenal football club.
“This deal, I think, is one of those moments in Arsenal’s history.
“If it happens, then I think the fans will turn massively.”
