The second period was going to be more complicated, with the reduction of Sallai's score (1-2, 67th) and the equalizer in stoppage time from the same Sallai (2-2) who sent the two teams into overtime.
This turned into a nightmare with the German team's third goal, signed by Gregoritsch in the 99th minute (3-2).
Behind, the Northerners tried to come back but without success.
