Lingard has entered the final year of his deal and has been offered fresh terms to extend his stay at the club. However, the England international forward 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, Lingard, who graduated through the academy to make more than 200 senior appearances, will be able to leave as a free agent at the end of the season and can begin negotiating with clubs outside England from January.
The 28-year-old 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 as England made it all the way to the final but returned to the team for the 4-0 win over Andorra on Sunday, scoring twice and recording an assist.
Lingard has struggled for opportunities at United under Ole Gunnar Solskjaer but impressed during a loan spell at West Ham United last season. In just 16 appearances following his temporary move in January, he scored nine times and won both the Premier League player of the month and Premier League goal of the month awards for April.
Despite interest from a host of other clubs from the Premier League and abroad this summer, Solskjaer was keen to keep Lingard at the club during the transfer window. So far this season he has made one substitute appearance in the 1-1 draw with Southampton.
There is increased competition for places at Old Trafford this season after the arrivals of Jadon Sancho and Cristiano Ronaldo. Winger Daniel James left for Leeds United on deadline day in a £30 million deal.
