Standard Liege want £7 million for striker Michy Batshuayi.
The Mirror says the Belgians are upset about Everton boss Roberto Martinez's interest in their powerful young attacker - and the fact the Toffees know about the 20-year-old's 'price clause.'
And they have told the Goodison club that they must meet the figure in one payment, and make it straight away.
While Standard want Batshuayi to stay for the rest of the season, the player fancies the move - and there have been talks.
