Bayern Munich announced on Sunday that Robert Lewandowski had returned to training. The Poland international picked up a minor ankle injury last week and was held out for Bayern's win over Darmstadt at the weekend. The injury occurred during Bayern's Champions League victory against Olympiacos.
Lewandowski's hold out was mostly a precautionary measure, as he's one of the few positions on the field where Bayern doesn't have a true backup. The team's adaptability under Pep Guardiola does give Bayern ways to play without a regular striker up top, but it's not an ideal situation that they want to be in.
Wolfsburg currently sit in third place in the table and are four points behind Bayern and Borussia Dortmund. Both FCB and BVB are tied in points with 15 at the top of the table. The three clubs are the only that have yet to lose a match this season. If Bayern want to beat Wolfsburg, they're going to need a healthy Robert Lewandowski.
