Fiorentina coach Delio Rossi has hailed the arrival of Amauri after victory over Siena.

The striker had not played for eight months due to a dispute with Juventus, but arrived on loan this week and had almost the full 90 minutes in today's Tuscan derby.

"It was crucial to win today, although we have to improve the distances between areas of the team. We need to be less frenetic," said the Coach.

"Amauri was coming off a long period of inactivity, but he is a great player and the mind can push on the legs even when they aren't in peak condition.

"This morning I made the decision along with Amauri for him to start the game. Will he play against Bologna midweek? We'll see.

"Fiorentina changed to a 3-5-2 system because I think it is better suited to the players at my disposal. I'm happy with the result, although of course we have to improve."
