Chelsea goalkeeper Jan Sebek has rejected a new contract offer.
The 20-year-old shot-stopper has returned to his Czech Republic roots and penned a three-year deal with FK Jablonec.
His agent, Viktor Kolar, told isport.blesk.cz: "For Jan it was a great experience to be at Chelsea.
"He has played regularly for the reserve team and a few times he has been involved with the first team and taken part in training sessions.
"The time has now come for him to attract more attention.
"He is bound to be an important member of the Czech U21 side and that is why we have decided to go with Jablonec, a side that traditionally gives young players an opportunity to shine."
