Chelsea will find out on Wednesday how much they must pay Exeter City for midfielder Ethan Ampadu.
The two teams were unable to agree a fee when the 17-year old moved to Stamford Bridge in July last summer and the matter will be decided at a tribunal in London.
Since joining Chelsea, Ampadu has gone on to make seven first-team appearances for Antonio Conte's side and has received two full international caps for Wales.
In 2016, the defensive midfielder, who can also play in central defence, became Exeter's youngest ever player when making his debut aged 15 years, 10 months and 26 days.
Grecians chairman Julian Tagg will be joined by manager Paul Tisdale, director of football Steve Perryman and finance director Keith Mason at the hearing.
Exeter are entitled to a compensation fee for the player, as he is a product of the club's academy and under the age of 24.
