Siena, coached by Giuseppe Papadopulo (pictured) picked up a fantastic victory over the Roman giants, who had Dejan Stankovic dismissed for swearing at a linesman.
"It is thanks to all my team-mates that we have been able to obtain this result," said Taddei.
"Everything went well today. We kept working hard and we were rewarded with the win.
"My two goals are dedicated to my team and to Enrico Chiesa - who I hope can return to the pitch soon.
"Now we must build on this result."
