Frankly, I can't understand how Germany, a team capable of scoring six goals against Slovakia, lost the first match without scoring any goals. There was no rotation in that match either. Woltemade, Wirtz, Gnabry and Goretzka played. They all played in this match too, so the lineup was almost exactly the same. I interpret the loss in the first match as a betting fix, there's no other alternative. Germany has the strength to beat any team when they want to and they proved it today. They secured their World Cup ticket.
Despite various problems, one thing you definitely can't accuse the German team of is match fixing. Most likely, they just couldn't get themselves in the right frame of mind for their first game against Slovakia, who were playing at home and were highly motivated.
Yesterday's match was like a training session where the main team trains the reserves and the Slovaks had no chance at all. I don't remember any dangerous moments in front of the German side. Although Slovakia should also be motivated, because a victory over Germany would have taken Slovakia directly to the World Cup.
It seemed like this was the main match of the day yesterday, but in fact, Montenegro vs. Croatia and Malta vs. Poland turned out to be much more competitive.
