If BVB wants to back to the glory days in Europe, they'd need to do lots of things, they need Goetze at fit. Goetze, Rues, Hummels, Subotic had played some international games in Euro and WC qualifier, they could get more experiences for different playing styles outside Bundesliga, but their central midfield is not really experienced outside Bundesliga, Seven Bender and Kehl still lack of experiences outside Bundesliga. I just read on newspaper, Lewa wants to leave BVB in next summer and just still one year in contact, BVB will have to sell in next summer, Lewa is not German, of course, he can choose another team have better financial potential, better European experience to get European titles, we can not require him faithful to the club like Germans. i read in
here BVB can buy Kevin Volland, but he's still very young, who can replace Lewa in Dortmund squad ? 30 million Euros is a big money for the team like BVB. The most important thing is they have to keep their key players like Hummels, Goetze, Reus for a long time and build up the team around them.
