Ousmane Dembele
When an athlete signs a contract with a new team, it’s down to the latter how much they choose to use them. Barcelona didn’t see the best of Dembele because he had terrible luck with injuries. The Frenchman failed to stay fit and spent a lot of time receiving injury treatment.

That’s a gamble every franchise takes when they buy a new player. But they decided that they wanted him to leave and threatened legal action if his agent didn’t force an exit. Dembele and his representation laughed because this was ridiculous and had zero hope of standing up in court (via Guardian).
