Yeah they should've but then I can't blame them much. Do you know what it means to hold Bayern at Allianz Arena? They'll definitely chicken out eventually.
Elversberg was completely outstanding for real, they outperformed Leverkusen and deservedly snatched all 3 points in an impressive fashion but we can't bank on them just yet. It's just the start. The problem is not having a good performance at the beginning, the question is can they maintain the performance till the end of the season?
A newly promoted team winning Leverkusen already shows how inconsistent other teams are. Let's see if the almighty Elversberg can survive Monchengladbach

I'll start to take them seriously if they can overcome their next two fixtures Borrussia Monchengladbach and Bayern Munich.
Newly promoted teams are very tricky teams to play against at the beginning like this.
Sure, but still unfortunate to see that Stuttgart became a slapstick show after their hard-earned equaliser.
I personally think Elversberg will snatch many points at home.
I mean their opponents will surely question their life choices when they suddenly have to play in the deepest province

Not to mention the stadium that most likely will be populated with huge cows - if there are not enough spectators

No seriously, I'm tempted to back them to avoid relegation.
