Germany's narrow victory was secured through Nick Woltemade's first-half goal. However, the team's overall performance was underwhelming, with them closely approaching the World Cup next year.
During the game, Wirtz was booed by Northern Ireland fans after some believed he exaggerated contact to gain a penalty for Germany. This incident sparked further criticism against him, making him an unpopular figure among the crowd.
Wirtz has since responded to the criticism on social media, stating "Successful international break." This comment comes after Germany earned maximum points during the international break.
Germany remains at the top of Group A with nine points from four games, closely followed by Slovenia, who trail by goal difference. Wirtz is set to return to action for Liverpool this weekend, as they host Manchester United at Anfield.
In order to regain his form, Wirtz will need to make a positive impact on the pitch, potentially by scoring or assisting a goal. This could help turn his recent performance around and silence his critics.
