Rumours of a possible move for Antony come amid his dismal form for United. He has failed to score or register an assist in any competition so far this season.
Coach Erik ten Hag said that the break from training Antony took after being accused of physical and mental abuse by his ex-girlfriend is the reason behind his slump.
"[He was] out for a couple of weeks so that broke the rhythm," he said. "Had a good pre-season but had a break so now has to get himself back in good form. It's hard work."
