Leicester City have agreed a deal in principle to sign Stoke defender Robert Huth, according to Sky sources.

It is understood that personal terms are still to be agreed between the player and the club where he spent the second half of last season on loan.

The fee for the German centre-half, who has made 187 appearances for Stoke, is thought to be in the region of £3m.

Sky sources understand that Leicester have also made a £7m bid for Huth's Stoke team-mate Steven N'Zonzi.

It is believed that N'Zonzi, who has one year left on his current deal, is keen on a move away from the Britannia Stadium and has rejected the offer of a new contract with the club.

Leicester's offer is expected to be rejected for the highly-rated French midfielder whose his performances last season earned him the Players’ Player and Supporters’ Player of the Season at Stoke.

Stoke boss Mark Hughes has already turned down a £3m bid from Spanish side Sevilla for the midfielder who has also been linked with Aston Villa and West Ham.

Nzonzi, who began his career with Amiens in France, joined Blackburn Rovers in 2009 for £500,000 before moving to Stoke in a £3m deal in 2012.
