Belgium born Ghanaian youngster Jeremy Doku has been rewarded a contract extension to 2022.
The 17-year old's recent rise in form has forced the club to tie him down with a year extension, which left fans unhappy.
But the rule in Belgium is that players from the age of 15 to 17 can only sign a maximum of three year contract until they are 18.
Doku will turn 18 on May 27, where the club could hand him a long term contract.
The Belgium youth international came close to joining Liverpool in 2017 after several English clubs showed interest in him.
Doku is enjoying a fine campaign since earning promotion to the senior side.
