John Stones will travel with Everton on their pre-season trip to Germany despite speculation surrounding his future at the club, according to a report..

ESPN claim that defender Stones flew out to Germany for two friendlies in Dresden as rumours intensified about his ongoing transfer.

The centre-back could become the most expensive defender in football history if his proposed £50million move to Manchester City goes through this summer.

The news comes just hours after City boss Pep Guardiola confirmed that he is interested in bringing the youngster to the Etihad before the start of the 2016-17 Premier League season.

The Daily Mail claimed that the Toffees rejected a £40million move for their prize defender earlier this month as Everton hold out for a fee of £50million.

The highest sum the Toffees have received for a player was £27million when Maroanne Fellaini joined Manchester United in 2013, while their record outlay is the £28million spent to entice Romelu Lukaku from Chelsea 12 months later.

Chelsea made three bids for Stones last summer of up to £35million, but new City boss Guardiola has earmarked the youngster as a key part of his revolution and is willing to meet the Goodison Park club’s demands.

The 22-year-old still has three years left on his current deal after joining from Barnsley in the 2013 January transfer window for £2million.

Stones has shown flashes of potential throughout a tumultuous season for the Merseyside outfit, playing in 41 games in all competitions, but he did not figure for England at Euro 2016 after being omitted in favour of Chris Smalling and Gary Cahill.

Toffees fans will hope Everton move to sign a replacement if he does go, as it would leave just two experienced central defenders at the club, Phil Jagielka and Ramiro Funes Mori.

In other Everton transfer news, the Toffees are on the verge of signing Aston Villa midfielder Idrissa Gueye.
