I don't hear about rumours related to German teams these days. Bayern Munich don't make many transfers so I'm already accustomed to that but it shouldn't be the same for Dortmund as well. They need to continue to make the squad stronger to keep their current level in the Bundesliga at worst. Otherwise they can even be under the threat of losing the second place in the league table. I don't say anything about the championship because it is obvious that Bayern Munich have a huge chance be dominant again.
