Italy are still to win a match in 2010.
Their 1-1 draw with Paraguay this week crowns the worst run of results for Italy in five years.
So far this year, Italy have drawn 0-0 with Cameroon, lost 2-1 to Mexico and drawn 1-1 with Switzerland, as well as Paraguay.
Italy's last victory was a 1-0 against Sweden in a November 2009 friendly played in Cesena. Juventus defender Giorgio Chiellini scored that night.
Italy's run of four games without a victory equals Lippi's previous worst winless streak which came back in 2005 after consecutive draws with Iceland, Norway, Serbia and Ecuador.
