Fulham are demanding £100m for Ryan Sessegnon.
The Sun reports the Cottagers are determined not to lose the 17-year-old without a fight.
The winger, who has been linked with Manchester United and Tottenham, was recently named Championship Player of the Year and is the first player from outside the Premier League to be nominated for the PFA Young Player of the Year.
Sessegnon would become the most expensive Englishman of all time should the reported £100million asking price be met.
