An experimental Italy side defeated Sweden in Cesena thanks to Giorgio Chiellini's first-half goal.
Having allowed Gianluigi Buffon, Fabio Cannavaro, Gianluca Zambrotta and Andrea Pirlo to return to their clubs following Saturday's draw with the Netherlands, Marcello Lippi gave Davide Biondini and Antonio Candreva their second caps and started with Giampaolo Pazzini up front.
That decision proved to be the right one after 28 minutes when the Sampdoria striker teed up Chiellini to head the Azzurri in front.
The world champions created the first chance of the second period through Pazzini, whose shot was blocked by Sweden goalkeeper Andreas Isaksson.
Erik Hamren was taking charge of Sweden for the first time following his appointment earlier this month, but his charges were struggling to fashion anything of note and despite several late changes it was Italy who ended 2009 on a high.
The Azzurri, along with the 31 other qualifiers from around the world, will now look forward to the FIFA World Cup final draw which takes place in South Africa on December 4.
