Nagelsmann’s side were dominant throughout, limiting the Scots. Germany opened the scoring in the first half as Wirtz fired into the bottom corner from the edge, before Musiala pounced inside the box shortly after to make it two.
Just before the break, Porteous was sent off for a shocking challenge inside the box, and Havertz stepped up to the spot to score the resulting penalty.
After the break, Germany continued to assert their dominance, and they made it four after Fullkrug, who came off the bench, sent a thunderous strike into the top corner.
Clarke’s side found a consolation late on as Rudiger headed into his own net from a Robertson free-kick, but it wasn’t enough to change the course of the game.
In the final seconds of the match, Can arrived on the edge of the penalty area to produce a well-placed shot into the corner, making it five for the Germans.
Up next for Nagelsmann’s men is their second group game against Hungary, while Scotland will face Switzerland.
