#5 Wolfsburg
Wolfsburg have the same number of points as Borussia Mönchengladbach, and are ahead of them only on goal difference. Wolfsburg struggled in the Bundesliga last year as well, but made up for it with a brilliant run to the Champions League quarterfinal.
They sacked Dieter Hecking as manager in October and appointed Valerien Ismael, but a managerial change is not all that is needed from Wolfsburg; they need their big players to step up. Andre Schurrle left in the summer and Julian Draxler will join PSG as soon as the transfer window opens. But Wolfsburg still have a good enough squad. The likes of Daniel Didavi and Jakub Blaszczykowski have not yet come to the party this season and Ismael needs them to contribute to support Mario Gomez.
Ricardo Rodriguez, who was once the subject of transfer interest from various other European clubs, has not had a good season at left-back. Overall, it has been a systemic failure for Wolfsburg.
