I think it would be ideal if he could return to his normal position as a full back. But the with problems with def mid he is the next best thing. A healthy Guidogan would have secured a place in the semis at least
For greek standards is relatively new city
But you are right.... It could have been a lot worst !! I like what i`ve seen so far...... well apart from the weather that is !

Yeah, Gundogan is the big one. His back problems seem to be chronic, though, so he might never get back to his top form.
Lahm in defensive midfield per se is not the problem, imo, but it is in the context of the current team. Lahm is the only DM, atm, so we're lacking physicality there. The false 9 forces us to rely on the OM for creativity, and if nothing comes from there, we can't even play over the wings, certainly not with our defensive full-backs. Leaning on my armchair, I think Loew analyzed the circumstances perfectly, and then made a lot of bad decisions in consequence...and I'm usually a fan of Loew.
I think it's time to move Lahm back to full-back, and bring Schweinsteiger and Klose back into the starting 11. Then again, we have no real back-up for Klose, so if we have to sub him, we're left without a real Plan B. Quite frankly, it's a bit of a mess.
