Edinson Cavani's first-half strike helped Napoli book their place in the final of the Coppa Italia with victory over Siena as they overcame a one-goal first-leg deficit and triumph 3-2 on aggregate.
Simone Vergassola's 10th-minute own goal paved the way for Napoli's comeback and when Cavani struck after 31 minutes it proved enough to send Walter Mazzarri's men to the final.
Napoli pushed forward from the start and had a fine chance in the seventh minute when Cavani was set up by Camilo Zuniga in the Siena box, but fired over from a very good position.
Vergassola's moment to forget came three minutes later when he clumsily deflected a free-kick from Ezequiel Lavezzi into his own net from 10 yards.
Napoli continued to press with Cavani bringing a fine diving save out of Zeljko Brkic in the Siena goal, then Marek Hamsik driving just over the bar from long range.
Napoli's second came from a swift counter-attack, with Cavani bursting out of the defence and finding Hamsik, who responded with a neat cross for the Uruguayan to head into the bottom corner.
Cavani should have added his second before the break when he missed the target after Brkic saved well from Gokhan Inler, and Napoli were almost made to pay when Emanuele Pesoli headed just over the bar for Siena.
In a good start to the second half for the visitors, Franco Brienza and Nicola Belmonte both came close, but Napoli's best chance fell to Lavezzi who shot over the bar in the 79th minute with only the keeper to beat.
Hamsik had a chance to make certain for Napoli five minutes from time when he was fed by Goran Pandev, but shot just the wrong side of the right-hand post before Brienza missed Siena's last chance from a tight angle.
