Germany are not THAT good. Read better please. I acknowledged right off the bat that Germany are great...just not as great as you say...Which is true. What you SHOULD do, is list 4 full teams...since that's what you claim to have. Not just copy Wikipedia's current list of players...and say, "See!" Weak. But I'll still reply to your list...
The Benders are MF's...you have them listed as defenders. Right off the bat, your list is suspect.
You have 2 great GKs and then you've listed 3 that no one's ever heard of, but we're supposed to take it on fact b/c you're Mr. Bundesliga. It would be the same if someone listed Jack Butland, Fraser Forster, and Jordan Pickford and said "England are 3 deep at GK." People outside of England might think that's true b/c they don't know, but everyone inside of England would say, "Yeah, they're three promising young(er) players..." In any case, gimme a break. Germany is 2 deep at GK. Period. Everyone can see that.
List your defenders as RB, LB, or CB please. You're just listing them as plain old defenders. I can't tell how many CBs there are (I think there are quite a few though) That's not how football is played. I can't agree or disagree that they're as deep as you say without being able to rank them 4 deep. Also, Mustafi is a joke. Get him off your list.
You've got 400 attacking midfielders. Pretty sure you're not going to line up that way. No disputing there are a lot of great players in Germany's midfield, but you can't play more than 2 or 3 at a time. Maybe if you add the Benders to MF as they should be, your list balances out. Maybe it doesn't. Either way. They're very deep in MF. Can't argue that. Perhaps they can go 3-deep here. Need to see and count AM's vs DM's to know for sure.
LOL @ Mario Gomez and Sandro Wagner as serious forwards. Gomez is/was half-way decent but is way beyond washed up. He won't sniff the national team, nor should he. He's servicable, at best. Sandro Wagner isn't that good at all. Neither are evidence of supreme depth. You're too thin at striker to say you're 4 deep. Honestly you only have enough good strikers for one team, not even a second. 1-deep at striker
You're probably 2-deep at every position with the exception of striker. Still impressive and still probably good enough to win the World Cup again...which they'll be the favorites to do.
By the way, out of curiousity, are you even German...or just some sort of weird German fan boy?
