Cardiff City boss Malky Mackay is favourite to succeed David Moyes at Everton.
The Sun says the Scot has just led Cardiff into the Premier League as Championship title-winners.
Yet he is said to be keen on the chance of a step up to such a big club, and there are suggestions an approach has been made.
If Everton do plump for Mackay, the Bluebirds would want £3million in compensation.
