Roberto Mancini described his Italy players as "extraordinary" after they booked a Euro 2020 semi-final spot with a 2-1 win over Belgium in Munich on Friday.
Nicolo Barella and Lorenzo Insigne put the Azzurri two goals ahead by the 44th minute, but Belgium pulled one back before the interval courtesy of a Romelu Lukaku penalty.
The Azzurri held on to extend their unbeaten run to 32 games, however, and will now play Spain at Wembley Stadium on Tuesday after Luis Enrique's side overcame Switzerland on penalties earlier in the day.
Italy have now reached the semi-finals of a major tournament for the 12th time – the only European nation to do so more is Germany (20 times).
The result also meant Mancini became only the second coach in European Championship history to win each of his first five matches in the competition finals after Michel Hidalgo, who won all five of his matches in charge of France at the 1984 edition.
"We deserved the victory," Mancini told RAI Sport. "The lads were extraordinary, and clearly we suffered in the last 10 minutes as we were really tired, but we could've scored more goals earlier.
"I didn't see 25 minutes of struggle at the start. There were chances at both ends, it was an open game. We only struggled in the last 10 minutes when Belgium started playing a long ball game.
"We had no minimum target. We just wanted to do our best. There are still two games to go, we'll see what happens.
"Let us enjoy this victory, then we can think about Spain. Congratulations to the lads, they did a great job."
Central to Italy's success was the colossal defensive display by Giorgio Chiellini and Leonardo Bonucci.
No player on the pitch made more clearances than Chiellini's six, while the pair helped reduce the Red Devils to just a solitary shot on target in the second period.
Bonucci expects a tough game against Spain but urged his team-mates to be ready to go into battle.
"Now we can keep dreaming with our feet on the ground," he said. "Spain are a great team, but we started this tournament with a dream in our hearts; let's keep it there until the end.
"There are two matches to go, the most difficult will be against Spain, who play similar to Belgium. They again looked as if they might not make it, but they got back on their feet, so it'll be a battle to the end."
The one sour note for Italy was the late injury suffered by Leonardo Spinazzola, with reports in Italy after the game suggesting he had ruptured his Achilles tendon.
"Leonardo had a great Euros, whoever replaces him will do just as well," Bonucci added.
