The Daily Mail claims that the defender has become the subject of intense Everton interest and a bid in the region of £18 million has been touted for the player who cost Sunderland only £5 million in January.
The player is said to be frustrated over an alleged broken promise regarding the offer of a new contract, while Moyes explains that he will be given a new deal on September 1 and fined in the meantime for his comments.
“Kone has been told we will renew his contract on September 1. We will honour something we said to him if we stayed up regarding a new contract,” Moyes told the Daily Mail.
“But because we're in the middle of the transfer window, we've said, 'Can we get our business done first?'
"I've only been in here two weeks, Martin Bain (chief executive) has only been in a few weeks, so can we wait and do it on September 1? We don't think that's too big an ask. He will be fined for what he said as well.”
To add insult to injury, Kone was said to have visited Liverpool upon hearing of Everton’s bid and spent the day taking photos of the city and with Everton supporters.
The Toffees are keen on bolstering their defensive ranks following the sale of John Stones and have seemingly identified Kone as the ideal man for the job following his terrific performances last season.
The 27-year-old joined the Black Cats from Lorient in January and played a key part in helping the club preserve their top-flight status, incidentally scoring twice in the 3-0 win over Everton which confirmed their survival.
