That's what has to be considered first. They haven't played with each other yet and it needs a few games at least to see whether they build a great defense duet. But from the looks I would say that this was a good choice and the height of both is remarkable. They are strong in their movements and 1.89 and 1.90 m respectively. That is a defense that is of high quality in any game situation. There could be late corners or free kicks and they can dominate high balls and low balls alike. If you compare that to other defenders who are only 1.80 m or even smaller, it could be the difference that is needed in some of those games when high balls become more common.
I'm just saying something, if Bayern with Min Jae and De Ligt in defense and with a striker like Harry Kane, it will be great to see this team, it could be that the Bundesliga will be very well dominated by an increasingly strong Bayern But the Dortmund that has shown so much? how will he do? It is known that this team is one of the toughest in Germany, and they saw that they had everything to win a Bundesliga, but they could not, sometimes I start to think that if all these signings were demanded by Tuchel to better secure his job and obviously the Team victories, I don't know but I think this Tuchel is giving nice surprises, maybe it's what Oliver Khan wants, to make this team one of the best in the world.
For the next season of the UCL I will like to see the performance of the German teams, because it will be from another world, I don't know, but to see so many stars and that they all manage them well in one team, it's something great, Harry Kane was the complement of a Muller who has been fighting practically alone without a Lewa to help him as before, as I say the Bundesliga, the UCL will be on another level.
Oliver Kahn is gone as he was sacked as he was fired from his position as the chief executive. It was a hefty divorce between Bayern Munich and him as they thought he is going to slap his successor in the face at the after-season party
The defense will benefit from Min Jae and as I said before having two players of that height in the defense that also have a high mobility at the same time can be a game changer. But in the Bundesliga the Bayern don't even need a game changer. As you have mentioned, Dortmund was served the Bundesliga title on a plate to their table by Bayern and yet Dortmund failed to take it. I have no idea what else has to happen that Dortmund can break this streak of Bayern of 10 consecutive 1st places in the Bundesliga. Everyone who is not a Bayern is hoping for a change and it doesn't even matter who the new champion would be, it is only important that there is a new champion soon.
