Roberto Martinez has slammed Chelsea over their pursuit of Everton defender John Stones.
The Premier League champions have already failed with a £20million bid for the England starlet, but are set to test the Toffees' resolve with an improved offer.
Martinez, talking after a 3-1 defeat by Arsenal in the final of the Premier League’s Asia Trophy in Singapore on Saturday, said further bids for the 21-year-old former Barnsley youngster would not be welcomed.
He said: "We pride ourselves on playing a certain way and educating our young players in a manner that they are going to always get attention from elsewhere and that is always a compliment.
"The other side is the disappointment of seeing a football club leaking such statements to the press and making it so open.
"That is not the way we would do it at Everton, we would not speak of a player who is registered at another club and there is no issue from our point of view - John Stones is an Everton player."
Martinez insists Everton are under no pressure to sell and has fired a warning shot to their Premier League rivals.
He added: "We are not a selling club. We are not a club that needs to be worried about what other clubs put through the press."
