John Stones has been linked to a move to Barcelona this January, but Roberto Martinez insists he won't be sold.

Stones was also the subject of multiple bids from Chelsea that Everton resisted during the summer.

“From our point of view the window in January will be to see if there’s anything that can help our squad," said Martinez. "We don’t look on it as a window to be really involved whether that’s buying or selling. It’s more a matter of continuity. It’s about developing competition for places between the ones we already have.

“I’m not worried at all – our best players will not be leaving in January. We’re not in a position where we have to make financial decisions or balance the books.”
