Host Germany began their quest for a record fourth continental title with a comprehensive 5-1 win over 10-man Scotland on Friday.
Florian Wirtz and Jamal Musiala scored inside the opening 20 minutes in Munich and Kai Havertz added a third from the spot before half-time after Ryan Porteous was sent off for a two-footed challenge on Ilkay Gundogan.
Substitutes Niclas Fuellkrug and Emre Can were both on target for Germany in the second half, either side of Scotland grabbing a late consolation through an Antonio Ruediger own goal.
Germany made a lightning start in Munich as they dominated possession, and it took just ten minutes to find the opener as Florian Wirtz fired in off the post to score the first goal of the tournament.
There was little let-up from the hosts, who just under ten minutes later had their second as Bayern Munich star Jamal Musiala, smashed the ball past Angus Gunn.
The three-time winners continued to lord matters over Scotland, whose dismal first half was compounded just before the break as a last-ditch, two-footed Ryan Porteous challenge resulted in both a penalty and red card.
Kai Havertz dispatched the penalty, giving the hosts a three-goal advantage at half-time.
The second-half was a largely similar affair as Germany continued to press on, keeping Scotland camped on the edge of their 18-yard box.
Niclas Fullkrug came on to add a fourth for Germany before an Antonio Rudiger own goal gave the Tartan Army something to celebrate.
Borussia Dortmund midfielder Emre Can, however, added a fifth with almost the last kick of the game to put the icing on the cake for Germany as they secured the biggest win in any opening European Championship game.
