Escola Varsovia have announced that they have signed an agreement to allow Polish goalkeeper Marcin Bulka to join Chelsea.
The 17-year-old was in London on Thursday to sign a long-term contract with the Blues, Polish website Przeglad Sportowy has revealed.
He trained with the Blues in April of this year when Dutchman Guus Hiddink was in charge of the team.
Reports have also claimed that Chelsea goalkeeping coach Hilario wants the youngster to travel to America to join the rest of the squad ahead of pre-season friendly games against Real Madrid and AC Milan.
It is unknown whether Bulka will be Thibaut Courtois's backup at Stamford Bridge or if he will be loaned out to gain experience.
