French agent Jean-Pierre Bernes says €200m for Tottenham striker Harry Kane is a realistic negotiating price.
Kane has been linked with Real Madrid for a summer move - and Bernes agrees a figure of €200m would take for him to be sold.
He told France Football: "There is now a permanent overbid. If (Philippe) Coutinho is worth €160m, put yourself in Tottenham's place when it comes to selling Harry Kane next summer.
"With him, it is likely to exceed the €200m again, especially in a year of the World Cup. €100m today, it has become an entrance fee to start talking."
