Burnley defender Michael Keane is attracting interest from Leicester

Burnley have turned down a second bid from Leicester City for centre-back Michael Keane, according to Sky sources.

The Clarets rejected an initial offer of £10m from the Premier League champions earlier this week and they have now knocked back an improved bid of £12m from the Foxes.

Keane, 23, played a key role in the heart of the Burnley defence as they won the Sky Bet Championship title last season.

The England U21 international began his career at Manchester United where he went on loan to Leicester for the 2012/13 season, featuring 27 times for the Foxes, who playing in the Championship.

Keane helped England U19's reach the semi-finals of the 2012 UEFA European U19 Championship and made Gareth Southgate's U21s squad for the Euro finals in the Czech Republic last year.

He joined Burnley on loan from Manchester United in September 2014 before making a permanent switch on deadline day in the January 2015 transfer window in a deal running until summer 2018.
