Burnley are determined to play hard ball over defender Michael Keane.

Manchester United are in pole position to sign Keane, who has set his sights on a return to the club he left for £2 million two-and-a-half years ago.

United have yet to make a formal offer for the England centre-half, even though one should be forthcoming once the Europa League final against Ajax in Stockholm next Wednesday is out of the way.

But despite Keane only having a year left on his contract, Burnley will not allow the 24 year-old to leave on the cheap and expect the clamour for his signature will help to keep the price high.

Liverpool, Spurs and Everton are also interested, even if United are the firm favourites to land him, and Burnley are likely to hold out for at least £30 million.
