Manchester United are wary of being used as a bargaining chip by Marquinhos' minders in new contract talks with PSG.
United boss Jose Mourinho is keen on the Brazilian, but won't hang about waiting for the defender to force through a move.
The Manchester Evening News says United have touched base to gauge how interested he would be in a Premier League transfer.
He is open to moving to England. United are mindful the Brazil international could be using the club as a bargaining chip to increase his wage packet from PSG's opulent Qatar Sports Investments owners.
At this juncture, United's interest is tentative and they are insistent Marquinhos will have to put pressure on PSG to let him leave.
