True, but so far Stones had one good season with us, the season every player played well and Moyes' defensive installments hadnt erroded yet. He had one good seasons, and two terribly shitty ones after, and is seemingly getting worse. I agree that Martinez is the reason why, but other young and promising players still had way better seasons than Stone, even though our team was crumbeling around them. Stones was a huge liability these past seasons, and even though big Ron might be able to correct his mistakes, I cannot shake the feeling John just wasnt made to be a CB. His vision and marking is on my mothers level, and he is even worse at winning headers. As a defencive midfielder he might become something special, but sadly, I dont think he will ever be the controlling/commanding CB we all want him to be. Without all the backwards goals Stones was directly responsible for last season, we would surely made the upper part of the table. I dont want us to sell Stones, but I would have felt a lot more safe last season with Van Dijk in our defence. He wins headers and know how to pass the ball without loosing it and creating pressure on his team. The footballing world might not rate his potential as high as Stones, but at this moment, most would agree he is a much better central defender than Stones is.
