Halfway through the 2012-13 season, Bundesliga clubs are hardly more separated than they were in August. Freiburg, Mainz and especially promoted side Frankfurt have been hugely successful and would all represent the German top flight on the international stage if the season were to end today.
The surprising form of some traditionally lesser clubs has left others with a mountain to climb if they are to achieve their goals. Schalke, Gladbach, Stuttgart and Hamburg are all separated by a maximum of one point, and in all likelihood will be competing for third place. Meanwhile, noveau-riche sides Wolfsburg and Hoffenheim are facing relegation.
The winter break will bring much-needed time for players to rest and reflect. And critically for clubs, it will offer the chance to bring in reinforcements. Read on for a rundown of the biggest names linked with moves to the German top flight during the January transfer window.
