Burnley have increased their asking price for stand-out defender Michael Keane in an attempt to prevent the England international leaving on the cheap, according to The Telegraph.
The centre-back is tipped to leave Turf Moor this summer, with former club Manchester United previously considered favourites for his signature for around £25m.
Keane left Old Trafford for Burnley for just £2m in 2015, and the Red Devils included a clause that ensured they would rake in 25% of any future transfer fee.
In the case that Keane's next destination happens to be Old Trafford, United would have to be given a discount, leaving them to pay just £18.75m rather than £25m.
However, The Clarets are said to have increased that sum by another £5m in order to recoup a satisfactory transfer fee, if he is indeed sold to Jose Mourinho's side when the transfer market resumes business.
Mourinho hasn't made a move just yet, but is thought to be keen on bolstering his back-line for the upcoming season. The Portuguese boss did not accomplish his goals in the Premier League during his first campaign, but a Europa League final win could be his saving grace.
Intent on avoiding another unsatisfactory season, Mourinho will look to spend again in the summer, and Keane could be one of the defenders who moves to Old Trafford.
The Red Devils will face competition, however, with Chelsea, Liverpool and Spurs all reportedly interested in securing Keane's services for themselves.
