Hummels is the real deal, as of course is Lahm. Boateng did surprisingly well in shutting down Ronaldo. Badstuber is the weak link, I think, but the alternative is Mertesacker, who isn't bad but is very slow. If Germany gets at least a point vs Netherlands, they'll win the group.
for me, lahm is the best defence player in the world. with him on the left side, nothing will happen. also he is very good in offence.
hummels was surprisingly good. yes he won the german titel twice, but when he played CL, he wasnt really good. but if he does a job like against portugal, everything will be fine.
boateng showed at CL half finals and finals that he can play really good. but he has to stay focused the whole game.
and badstuber isnt bad. he is just very jung, i guess thats his biggest problem.
i think the biggest problem for germany is that schweinsteiger still doesnt looks really fit and müller didnt made his best game against portugal.
should both show again a bad game, it will be dificult to win against netherlands
