Germany suffered a shock 2-0 defeat to Slovakia in their opening Group A game in Bratislava, but responded well to see off Northern Ireland on Sunday thanks to goals from Serge Gnabry, Nadiem Amiri and Wirtz.
Julian Nagelsmann's side made a strong start to the game at RheinEnergieSTADION, with Serge Gnabry getting on the end of Nick Woltemade's through ball before chipping Bailey Peacock-Farrell to give the hosts an early lead. Germany continued to dominate the ball through the opening half hour, but Northern Ireland found a way back into the game after capitalising on Antonio Rudiger's sloppiness. Crystal Palace's Justin Devenny's corner kick found Isaac Price, who managed to get away from the Real Madrid defender and slot in a delightful equaliser on the volley to make it 1-1 heading into the half-time break.
Germany continued to look out of sorts in the first 15 minutes of the second half, until Peacock-Farrell's misjudgement of a lovely David Raum's pass allowed Nadiem Amiri to nip in and score into an open net to put Nagelsmann's team back in front. Liverpool star Wirtz then rounded off a crucial victory for Germany with a perfectly struck free-kick from 20 yards out to give himself lift-off for the season and put his country back on track in World Cup qualifying.
