Bertrand Traore has joined Olympique Lyonnais from Chelsea for in the region of £20m.
The winger was on loan at Eredivisie side Ajax last season, and he netted 9 times in 23 appearances.
When he joined The Blues, they got him for free, now they look to net £20m off him. Considering he has only played for Chelsea 10 times, that is a magnificent deal.
This proves the loan system which Chelsea have adopted does work, and allows for funds to be put forward in order to sign first team players.
