Fiorentina's breach of contract claim relating to Mohamed Salah has been rejected by FIFA's dispute resolution chamber.
FIFA has rejected Fiorentina's protest over Chelsea's decision to loan Mohamed Salah to Roma last season.
Egypt international Salah signed for Chelsea from Basel in January 2014 and went on loan to Fiorentina a year later, making 16 Serie A appearances for the club.
The 23-year-old winger was then loaned to Roma last season, prompting Fiorentina, who expected to have the player again in 2015-16, to claim a breach of contract had taken place.
