Martinez has a long term project in place. We can't compete with the top four financially, and the only way we possibly could is to invest in young talented players with lots of potential and for those players to gradually develop, over a few seasons, into top class footballers. If we sold Stones, it would completely contradict that policy and send out the wrong message.
If Stones isn't agitating for a move, we should keep him, even if Chelsea offer £50 million. We have to stick two fingers up to Mourinho, Chelsea and the baying media, who are beside themselves that he hasn't joined Chelsea yet, and are so desperate to keep the story alive that they've now resorted to making up stories about Stones putting in a transfer request.
The whole media circus has been disgusting (though not surprising). Everton might be skint, but we are still, historically, a massive club and deserve to be treated with respect. I hope Martinez is allowed to stand his ground and tell the lot of them to do one!
