Manchester United are reportedly keen to put together a part-exchange deal for West Ham United midfielder Declan Rice.
While the Hammers star has previously been linked with Chelsea, speculation regarding a switch to Stamford Bridge has ended since the departure of Frank Lampard.
With a new centre-back and a younger central midfielder potentially in his sights, Ole Gunnar Solskjaer is allegedly keen to sign the England international this summer.
Lingard has already made a loan transfer to East London, contributing three goals from his first four appearances for the club.
The report adds that United may also have to be prepared to pay at least £20m in order to entice West Ham into formal discussions.
