Reports are claiming that Everton will be looking for bids of £50M if Ross Barkley does not sign his contract.
Ronald Koeman has said that he wants to know the intentions of Barkley, who is mulling over a contract offer, by the end of the week.
A decision is highly unlikely by then, extending the impasse into potentially volatile territory as Koeman has said the player will be sold if he does not put pen to paper.
In those circumstances, reports claim that Everton will demand a fee similar to the one they received for John Stones a year ago, despite the fact Barkley has only a year remaining on his current deal.
The rationale for such a figure is the current standing of Barkley, his age, and the likely calibre of club who will show an interest. Tottenham have long been considered the most likely destination but new reports suggest Arsenal are now showing interest.
The fact that Barkley's contract is running down is not considered to be a factor in his price this summer, with the World Cup approaching next year. To remain in contention, Barkley must play at the highest level, and cannot risk being used sparsely, if at all, by Koeman, should he choose to play out the final year of his contract.
