Ex-Manchester City manager Mancini has won just one of six matches since taking charge earlier this year and none of the past five.
A solitary point from last month's meetings with Poland and Portugal has left the Azzurri bottom of its UEFA Nations League group and at risk of slipping into League B.
Mancini is reluctant to place emphasis on present results, insisting he is focused purely on regeneration as Italy seeks to heal the wounds of missing the 2018 FIFA World Cup.
"This journey started in May. The objective is to build the team and get it ready for Euro 2020," Mancini said.
"When we started, our goal was to rebuild the side and make a good impression in the Nations League, but that is it. It's impossible to build a new team in five games.
"When we find a group that can do great things we will not have many problems forming a team for the Euros.
"The Nations League was created to give more value to matches, but I don't see the need to make drama out of it. We will try to win but it doesn't change anything."
Captain and veteran defender Giorgio Chiellini concurred with his head coach, calling for Monday's (AEDT) clash with Poland to be assessed in view of the team's longer-term ambitions.
"It's not a final, it's not a play-off, it's just an important push towards Euro 2020. There is a long way to go yet," the Juventus man added.
Italy's final UEFA Nations League assignment after the Poland trip is a visit from European champion Portugal on 18 November (AEDT).
