Just try to imagine how strong Borussia dortmund is when it doesn't always sell its best players, of course it can win the Bundesliga.
That was already so often written here and the problem is they want to keep this good players but they cant effort the money for it.
If they would have some sponsor like other clubs have they would have for sure good players and would a real opponent for Bayern Munich.
But they can win the team they have now also the German League.
While I think Dortmund even with the players they have now is a very strong team I can also say that they are far far far away from winning the title in this upcoming season and in fact if I find a bet that says Dortmund not to win the Bundesliga I would bet a lot of money on such outcome.You may say why I am so radical in thinking and you are right but I am because I have seen what they missed in the last game of the last season where they had the title in their hands and they threw it away,it takes a whole lot of time to get out of such psychological blow and that is the reason I have no doubts Dortmund will not be Bundesliga Champions in the upcoming season.
