Lingard, 27, has fallen down the pecking order at Old Trafford and failed to make Ole Gunnar Solskjaer’s matchday squad for the 3-1 defeat to Crystal Palace on Saturday.
The England international has spent his entire career at Manchester United, graduating through the club’s academy to play 207 matches for the first-team and win the FA Cup, EFL Cup and Europa League.
With Lingard frustrated with his lack of game-time at the Theatre of Dreams, a move to Tottenham – to work under his former manager Mourinho – may appeal.
ESPN say Mourinho is keen to welcome Lingard to north London and has asked Tottenham chairman Daniel Levy to attempt to secure his signature before the summer transfer window closes on October 5.
It is claimed that discussions between intermediaries are now underway, with Lingard open to the move in order to feature more regularly.
Red Devils boss Solskjaer, though, wants Lingard to stay in Manchester and has reportedly reassured him he will receive opportunities during a hectic season.
For Mourinho to sign Lingard, Tottenham may need to offload Dele Alli, who was left out of Spurs’ squad for Sunday’s trip to Southampton.
Tottenham have signed Gareth Bale and Sergio Reguilon from Real Madrid this week.
