Fulham boss Slavisa Jokanovic insists Tomas Kalas can still make it at Chelsea.
The 23-year-old has been on Chelsea's books since 2010, when he signed from Czech side Sigma Olomouc for around £5million, but has made just four appearances for the Blues and spent most of his career on loan.
“First of all Tomas has been very good at the beginning of the season," Jokanovic said.
“He has done an important job for us and I believe this is a good place for him to get the benefits of playing more games as it is not his first loan.
“Last season he didn't play many games at Middlesbrough and generally we are so close to Stamford Bridge here, so they can check easily if Tomas is a player can help at Chelsea in the future or not."
