Giorgio Chiellini concedes Italy were fortunate to have beaten Japan in the Confederations Cup on Wednesday.
The Azzurri won an enthralling match 4-3 after initially being 2-0 down and surviving a number of scares at the back.
“We were a little lucky in terms of the final score,” the Juventus stopper commented after the game in Brazil.
“This encounter has taught us one lesson – no matter how tired we are, we have to be more of a team. We risked too much.”
The victory, coupled with their 2-1 over Mexico in their first game, has now assured the Azzurri of a place in the last four.
“The result is decisive as it propels us into the semi-finals,” added the former Livorno and Fiorentina stopper.
“The first objective that we set ourselves has now been achieved. Now we need to think about the game against Brazil with the right focus, even if the semi-final will be a more important fixture.”
Italy and Brazil will meet on Saturday in a match that will decide who wins the group and who will finish second.
The hosts currently top Group A as they have a superior goal difference.
