I see huge class difference here and I see different season targets here.
Aue finished 15th placed last season with one of the worst offensive and defensive lines (31:55). They were quite lucky to avoid the play-off spot and probably will search at least a middle table finish this season. Interesting fact is that Aue won both of their matches agianst St. Pauli last season, but IMO that was quite lucky results, especially away from home.
St. Pauli finished 4th in the table and missed the chance to fight for promotion. This season I expect them strong motivated for the straight promotion and I rate them capable to do it as they are one of the best sides in the league for sure. Pauli made good preparation before the season, playing matches with 5-2-0 in their 7 friendly games, beating Wolfsburg with 3:1. I expect them to continue that positive run and to win important 3 points tonight.
