Lorenzo Pellegrini scored a stunning bicycle kick goal for Italy in a 2-0 win over Denmark.
Luigi Di Biagio made the victory safe through former AC Milan starlet Andre Petagna to justify being labelled as a favourite for the tournament.
Germany, also strongly tipped to go far in Poland, dispatched Czech Republic 2-0 with former Arsenal star and new Bayern signing Serge Gnabry on the score sheet.
Max Meyer grabbed the opener against the Czechs, curling a low shot into the bottom right corner after coming in from the left.
Gnabry then side-volleyed home to double the lead and make Gunners fans bemoan his sale a year ago to Werder Bremen.
Italy will next face Czech Repubic on Wednesday with Germany facing Denmark, both knowing a win should be enough to qualify, even as a second-placed side.
The pair square off in the final game in a mouth-watering clash that will surely decide who wins Group C.
Attention now turns to England after their goalless draw with Sweden, knowing they need to pick up a win over Slovakia tomorrow.
