Fiorentina ace Stevan Jovetic struck twice in a sensational display as they stunned Liverpool 2-0 in last night's Champions League clash.
"Jovetic has done more than a step up in quality," said Viola coach Cesare Prandelli.
"Last season he clearly had the quality, but it was most often used only for his own moves. From this term he is playing at the service of the team with the right movements.
"I have to compliment him, because he arrived for pre-season training with a great deal of belief. He is scoring regularly, is more relaxed and happy.
"Last year he tried a bit too hard to score and with that attitude it often doesn't happen for you. The goal comes when you are relaxed."
