Wolfsburg look a shadow of the team they were last year. To compound that, they lost their captain and midfield enforcer, josue ( not sure for how long). The main strength they had last season was their organisation defensively, as their defenders are close to rubbish ( last night they had Madlung and Barzagli !). Magath does that very well and Veh will need to do something about that because once the CL comes along they might have more troubles.
Bayern look good and Robben did dominate because he is a good player. This guy did dominate both the EPL and La Liga, so he is not just an "average" player. But they won't have it easy imo, even in this game they needed a mistake to score the first game and throw wolfsburg off their game.
