Three-times European champions Germany shrugged off their opening game loss and announced their arrival as serious contenders at Euro 2020 with an emphatic 4-2 win over highly-rated Portugal in their Group F match on Saturday in Munich.

Cristiano Ronaldo had given the defending champions a 15th minute lead but Germany went in at the break 2-1 up thanks to own goals from Ruben Dias and Raphael Guerreiro.

Germany went on the attack from the off in Munich, thriving on the vibrancy offered by their wing-backs. The man on the left, Robin Gosens, even found the net but his well-taken finish was ruled out for offside. Back they came, wave after wave, but Portugal repelled them before the sucker punch: Cristiano Ronaldo starting and finishing a thrilling counterattack.

Die Mannschaft picked themselves off the canvas, dusted themselves off and resumed the barrage. The pressure told with two own goals in the space of five minutes late in the first half, with Rúben Dias and Raphaël Guerreiro inadvertently beating Rui Patricio. Portugal were stunned, unable to muster a response; and it got a lot worse before it got better.

By the hour mark it was 4-1 and the holders were out on their feet, Kai Havertz tapping in before the brilliant Gosens headed in a cross from Joshua Kimmich. Joachim Löw rang the changes, with half an eye on Wednesday, and Portugal improved, pulling one back through Diogo Jota. Renato Sanches rattled the post with a stunning strike but the damage was done.

Germany's Robin Gosens was named the Star of the Match.
