Stones recently suffered a hamstring injury, but the England international central defender is now fully fit.
Martinez has assured the fans that the 21-year-old, who can also play as a right-back, is ready for the final weeks of the 2015-16 campaign.

Everton will return to action on Saturday afternoon when they take on West Ham United at Goodison Park in the Premier League.
West Ham are having a good season and will head into the game full of confidence.

Given West Ham’s recent form, the London outfit will fancy their chances of picking up all three points against Everton.
Playing at home, though, is going to give the Toffees an advantage, and one suspects that the first goal will be huge important in deciding the outcome of the match.
