A stunning strike from Isaac Price was not enough for Northern Ireland as second-half goals earned Germany a 3-1 World Cup qualifying win to ease the pressure on Julian Nagelsmann.
Germany came into the contest reeling from Thursday's shock 2-0 defeat in Slovakia, their third consecutive defeat leading to stinging criticism of Nagelsmann in the German press.
Price’s 34th-minute volley cancelled out an early goal from Serge Gnabry and gave Northern Ireland genuine hope of getting something out of the game, but quick-fire goals from substitute Nadiem Amiri and Liverpool’s £116million man Florian Wirtz settled it midway through the second half.
But though Northern Ireland left Cologne defeated, for long spells they were the ones causing Germany problems in a performance that can serve as another marker for this young side.
