Italian side Fiorentina, have tried to drag Chelsea to the mud after the sale of former Roma winger Mohamed Salah to Liverpool.
Chelsea have hit out at Fiorentina and have accused them of trying to “extort” money from Chelsea in the Salah deal.
Salah joined Fiorentina on loan from Chelsea in January 2015 for the remainder of the 2014-15 season.
Fiorentina alleged breach of contract when the Egyptian winger moved to Roma on loan for the 2015-16 season in a deal which later became permanent.
However, FIFA dismissed Fiorentina’s complaint in May 2016 and, 13 months on, CAS has dismissed their complaints as well.
A spokesman for the Blues have revealed Chelsea’s unhappiness with Fiorentina: “Chelsea’s position throughout this case was that Fiorentina had acted in bad faith in bringing a claim which was totally unfounded.
“We are pleased that the CAS Panel came to the same conclusion, with Fiorentina’s case rejected in full and costs awarded to Chelsea and the player.
“We look forward to the full decision being published so that everyone can see the lengths that Fiorentina were prepared to go to in order to extort large sums of money from Chelsea and the player.”
