Saint-Etienne have confirmed Jordan Veretout is joining Fiorentina.
The midfielder has been on-loan at ASSE from Aston Villa this past season.
“We know him well as a man and a footballer, but frankly we were surprised and disappointed by his conduct," ASSE chief Dominique Rocheteau stated.
“He didn't respect the word he had given us and the agreement we had with him.
“His arrival had all been organised, but then told us he wanted to go to Fiorentina.
“His choice is a sporting one. Now we've discovered that we weren't his first choice."
