Bertrand Traore signed his first professional contract at Chelsea in 2013 at the age of 18 but was not registered until January 2014

Chelsea were given a transfer ban after 150 rule breaches involving 69 academy players over several seasons, says a judgement published by Fifa.

The two-window ban, which ends in February 2020, was upheld by the world governing body in May after an appeal.

New details of the case came to light after being published on a Fifa legal website
