This is just the start of the season, which doesn't guarantee St Pauli's Bundesliga survival. Previously, St Pauli was fortunate to hold on draw against Borussia Dortmund.
If Dortmund hadn't received a red card, St Pauli might have lost.
Against Hamburger yesterday, St Pauli was also fortunate to only have 10 men. If Hamburger had played with 11, the final result might have been different.
St. Pauli isn't a particularly strong team in the Bundesliga, but with their early-season surprises, they could continue to be wary of the other big teams in the Bundesliga. With St. Pauli already on such a high, they'll naturally be motivated to continue playing exceptionally well in their upcoming matches, even against strong teams. And if the team can maintain their place in the top four this season, it could be quite an achievement for them, although I personally still doubt that will happen for St. Pauli.
