Everton has rejected an improved bid from Chelsea for Anthony Gordon.
Chelsea initially offered £40 million and then improved the offer to £45 million ($54 million).
Chelsea will now decide whether to make a third offer for England under-21 winger Gordon, who has previously attracted interest from Tottenham Hotspur and Newcastle United.
Sources have told ESPN that Everton value Gordon well in excess of £50m but would prefer to keep him given they have already lost Richarlison to Tottenham this summer.
