Sergio Parisse celebrated Italy's most successful Six Nations following their 22-15 victory over Ireland at the Stadio Olympico.
It was the Azzurri's first victory in the fixture since joining the tournament in 2000 and combined with their triumph over France, it completed their best overall championship performance.
They also registered two wins in 2007 - against Scotland and Wales - but Parisse insisted the quality of opposition they have mastered this year sets 2013 apart.
"You can't compare this Six Nations with 2007 because we have secured wins against two squads with a lot of history, two of the strongest in the world," the Italy captain said.
"We're a squad that's improving. We play France and Ireland in the group stage of the 2015 World Cup and we have sent a strong message to them.
"There were a lot of positives in this game from a psychological point of view because there was a good balance between our backs and forwards.
"In this Six Nations we have managed to put a lot of teams under pressure. We played against some great players like Brian O'Driscoll, but have nothing to be envious of."
