Kroos has really improved as a player lately. Him and Schweinsteiger are looking very good so far.
It's insane when you think about Dortmund who've won the league twice in a row now and have some of the best attacking talents in the world, and yet Hummels is the only one who's got a shot at starting for the national team this summer. And that's mostly because Mertesacker hasn't played for a couple of months.
