Napoli defeated Siena 2-0 on Wednesday to reach the Italian Cup final on a 3-2 aggregate and will face Juventus in the May 20 final where they will look to end their 22-year wait for silverware. Fired-up by their Champions League exit to Chelsea, Napoli went ahead after just 11 minutes through an own goal from Simone Vergassola. Uruguayan striker Edinson Cavani added the second in the 31st minute after a swift counter-attack sparked by Ezequiel Lavezzi and Marek Hamsik. Juventus reached the final on Tuesday after knocking out AC Milan. The semi-final second leg ended 2-2 but Juve went through 4-3 on aggregate.
