Lingard is seeking assurances about his first team prospects this season.
The 28-year-old is into the last months of his current deal and has been offered an extension.
However, Lingard has turned down United's initial approach and is keen to ensure he will get the opportunity to play regularly before making a decision about his future.
If a new contract is not agreed with United, he will be able to leave as a free agent at the end of the season.
Lingard will also be able to negotiate with clubs outside England from January.
The England international is determined to find regular football in order to keep his place in Gareth Southgate's England squad ahead of the 2022 World Cup in Qatar.
He narrowly missed out on a place in the squad for Euro 2020.
