Fulham have completed the signing of Tomas Kalas from Chelsea on another season-long loan.
The Czech Republic defender, 24, rejoined the Whites after signing a new four-year Chelsea contract.
He impressed while on loan at Craven Cottage last season, helping Fulham reach the Championship play-offs.
Tony Khan, Fulham’s vice-chairman and director of football operations, told the club website: “It’s a pleasure to welcome Tomas Kalas back.
“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.”
