For this particular match, although Flores was using a 4-4-2 formation, Atletico Madrid's defense started right from their forwards.
Since they were struggling to get results in La Liga, the Sheet Army had pinned all their hopes on the UEFA Europa League and the King's Cup.
This spurred their players to fight with extraordinary desperation during the match, with the entire team pressing frantically for the ball.
But the most important factor was the speed of their defensive retreat.
Nearly every time Dortmund carried the ball past the halfway line, Atletico Madrid had already fallen back into a full defensive line.
And Dortmund themselves weren't a team that excelled at passing and possession.
As a result, moving the ball out of the midfield became increasingly difficult.
Combined with the fact that the Atletico Madrid players were very hands-on, it was no wonder Götze had nearly lost his composure moments ago.
Although they were leading 1-0, the lead was far from secure.
