Chelsea defender Tomas Kalas has signed a new contract with the Blues that will keep him at the club for four more years.
The 24-year-old spent last season on loan at Fulham and will continue his spell at Craven Cottage next season as well.
Fulham vice-chairman and director of football operations Tony Khan was delighted after the two clubs reached an agreement for the transfer.
"It's a pleasure to welcome Tomas Kalas back to the Fulham Football Club," he told the club's official website.
"We appreciate Tomas so much after the way that he battled for us last season, demonstrating not only tremendous skill but also great heart and determination.
"We're very excited to have him here again as one of us as we prepare for our next battle, and what we hope will be a great season! COYW!"
