Chelsea are ready to sell Tomas Kalas this summer but are demanding £10 million from potential suitors.
The Mirror, as cited by Football League World, claim Fulham are keen on a permanent deal after the defender impressed with the Cottagers whilst on loan.
Fulham are preparing for life in the Premier League and Kalas does not appear to have a future at Stamford Bridge.
The defender has not ruled out returning to Chelsea and fighting for his place, but the Whites could offer him regular first-team football in the Premier League.
Kalas has become a fan favourite after two years on loan with Fulham and he played a key role in their promotion from the second tier.
The 25-year-old has been at Chelsea since 2010 but has been unable to break through into the first-team squad, making just a handful of appearances throughout his time at Stamford Bridge.
