Everton boss Roberto Martinez says Chelsea captain John Terry has broken Premier League rules by speaking about the future of defender John Stones.
According to the Guardian, Terry told reporters that John Stones is "one for the future" at Stamford Bridge, a comment deemed unacceptable by the Everton manager.
"That is wrong; that is illegal," Martinez said.
"The rules don't allow you to comment on players who are registered at other clubs in that open manner. That is disappointing.
"We haven't been in that situation.
"The whole John Stones situation has come through the media because a club made a bid and made it public. We have never been in a situation of commenting.
"We have a very talented young player who really has the potential to be the best centre-half England has produced, so you are going to get that attraction. That is natural, healthy and very, very positive.
"But a player can make a decision when the clubs say he can make a decision. There is nothing to make a decision on. There is no negotiation. There is no relationship between the clubs in terms of trying to find a deal."
