Based on that the fact that Dortmund simply have the better overall team, failed by its defence and playmaker void since Gundogan left.
Leipzig might lose a couple of players, they have a rich company behind them, but still not the spending power to spend an outrageous amount of money and Dortmund's finances are getting better and better, so they can now keep their players and sign some other good ones.
Leipzig is a surprise package this season. They've taken the league by storm, but the chances of them going big aren't high. Teams will find ways to exploit their weaknesses and only then will we see how they cope. Dortmund have everything in place already for a team to properly challenge Bayern from the management structure to experience at this level. Only thing lacking is some key components in their team + consistency.
I really don't see it,you are basically saying BVB just being failed by half of the team while teams might find way to exploit Leipzig weakness?
BVB weaknesses are much worse and need bigger work
Their late Arsene Wenger approach works against them IMHO,they have put themselves into a situation that many of the star players would want out. they are step for a player to go to the real big clubs.
Leipzig approach for last years has been slowly building a team that can contend,they are now the exciting successful team. They don't have power to spend now b/c they have just reached Bundesliga,expect them to spend more every year. Doubt they will sell players as easily as BVB
Teams failed to exploit Bayern weakness, teams only exploited for weaknesses if they stagnate and stop developing,it is more up to the team itself than the opponents. we will see if that is the case for Leipzig but surely it has been the case for BVB for few years btw.
It is all speculative at this point,but I don't think there is anything conclusive about Leipzig situation other than the fact they are currently doing much better than BVB
