Roberto Martinez has claimed that Chelsea are trying to unsettle John Stones in their pursuit of the Everton defender.
Chelsea reportedly came in with a £20m bid for the centre-back earlier this week, and their conduct has upset the Toffees boss.
The Daily Mail quotes Martinez as saying: "One thing is clear, that we pride ourselves in playing a certain way and educating our young players in a manner in which they will always attract attention from elsewhere and that is a footballing compliment.
"The other side is that another football club is making a statement in the press so openly I don't think that is the way we would do it at Everton.
"We would not speak about a player that is at another club and there is no issue from our point of view: John Stones is an Everton player full stop."
Stones and Everton were in action this afternoon, as they lost 3-1 to Arsenal in the Asia Trophy final.
