It's been widely reported this morning that Spurs have made an official offer for the highly rated 20-year-old, but Everton are reluctant to sell their young defender and are unwilling to negotiate any possible deal.
Stones is a product of the Barnsley youth system and joined Everton for £3m in 2013. The youngster had a solid first season at Goodison Park making 21 appearances for the Toffees.
A host of assured performances at the heart of the Everton defence lead to an England call up for Stones, and the 6"2 defender was eventually listed as a stand by for Roy Hodgson's 23-man World Cup squad.
Big things are expected of Stones this term after such a strong debut season, and Roberto Martinez will be keen to ensure the youngster's immediate future is in an Everton shirt.
Mauricio Pochettino is desperate to bolster his defensive ranks at White Hart Lane, and with Michael Dawson reportedly in talks ahead of a move to Hull, the Tottenham manager may see Stones as the ideal replacement.
It was a core of British players that acted as the spine in Pochettino's successful Southampton side last season, and the Argentinian manager may now wish to build a similar set up at Spurs.
But with Everton clearly determined to hold firm over the future of Stones, the Tottenham manager might have to look elsewhere.
There is yet to be any report regarding the proposed fee offered by Spurs, but it's understood that the North London club would have to make a serious cash offer if they are to have any chance of prising the defender away from Goodison Park.
