The Clarets are under no pressure to sell the England international following the centre-back's impressive season at Turf Moor
Burnley manager Sean Dyche says it is "not rocket science" to work out there are big clubs interested in signing defender Michael Keane.
Manchester United are reportedly frontrunners to re-sign the centre-back, who left Old Trafford two seasons ago, while Chelsea, Everton and Liverpool are also said to be in the hunt.
Burnley will reportedly demand £25million for Keane, but Dyche insists the England international, who is under contract to 2018, remains focused on his current club.
