Manchester United are due a sizeable windfall when Michael Keane inevitably leaves Burnley.
The central defender is attracting admiring glances ahead of the January transfer window, with the Clarets having turned down bids from Leicester City in the summer.
Sportsmail understands United are set to pocket 25 per cent of any transfer fee if Chelsea target Keane was to exit Turf Moor.
Burnley would only contemplate selling the 23-year-old for ‘silly money’ in the next transfer window but there is an acceptance he is likely to seek pastures new next season.
