Roberto Martinez has made it vehemently clear that Everton will not be selling any of their key players this winter.

Once again, young defender John Stones has emerged as a transfer target for Chelsea but Martinez insists that the 21-year-old, nor any other key Toffees, will be departing Goodison Park in January.

"I am not worried at all — our best players will not be leaving in January," said Martinez.

"Our focus is on being as strong as we can together."

To marry Martinez's words, recent reports suggest that Everton have slapped a massive £45million price tag on the seven-time England international.
