The Burnley defender has been the subject of speculation surrounding a return to Old Trafford after a fantastic season with the Clarets.
Keane and Lingard came up through the United youth ranks together, and could be reunited this summer, with a reported £25m bid tabled for the 24-year old.
The deal would give United a discount given the 25% sell on clause included in Keane's contract from when the Red Devils sold him to Burnley in 2015.
