We will definitely see how the second half of the season goes for Borrussia Dortmund who re also struggling this very season. Stuggart are just good because of a single person pushing them forward. Liepzig off course has more than a single person who knows how to play and push the squad and his teammates forward. They're trying to move at them own speed if you ask me. Liepzig don't just have Openda bit also Xavi Simons the brilliant young midfielder.
I don't rate them too much and higher because they had a golden opportunity but couldn't make good use of the chances last season,they should have won the game and lifted the Bundesliga League Competition but they still be messing up around as they bottled the league completely.
Firstly i will say I find Stuttgart in a very good form and i think they will go a long way to qualify for the European competitions most likely the biggest of them which is the champions league. But do I count them as league contenders? No. Just like Freiburg and Union Berlin last season they will lose the tenacity to keep carrying on. There goals have come all between just two players which is Guirassy and Undav. With Guirassy already having admirers in the winter transfer window I will say they could lose him to any of the big clubs with also his release Clause not that much and him looking for another challenge and not signing new contract the sale might be evident.
As for Leipzig I will say I think they still are still a little bit raw to compete for the title. The team is full of young squad that need leaders because the second half of the season is always full with character challenging moments. So I am ruling them out this season.
As for Dortmund I seriously also feel they blew away the only chance to end Bayern Munich dominance last season. This season they are not still far behind because last season they actually went all the way in the second half of the season and nearly won it. Should they show same character again this season they could go all long. But my best bet is Leverkusen to challenge Bayern Munich for the title this season
