Micheal Keane will spark a bidding war this summer with Manchester United, Tottenham Hotspur, Liverpool and Everton all vying for the highly-rated Burnley and England defender’s services.

Jose Mourinho is eager to bring Keane back to Old Trafford two-and-a-half years since he was sold to Burnley for £2 million by Louis van Gaal, his predecessor as United manager.

United negotiated a clause when they allowed Keane to leave for Turf Moor in January 2015 that entitles them to 25 per cent of any sell-on fee.

If United successfully re-sign Keane, that would effectively mean a discount on a transfer fee that could surpass the £30 million mark given the widespread interest in the 24-year-old centre-half.

Burnley are mindful of the £47.5 million fee Manchester City paid Everton for John Stones, another young England defender, last summer.
