Bayern brought themselves into a good position with those late goals, but that doesnt mean they are though now. Actually its that exact thinking that often leads to their demise. Man Utd still has a very strong team and tend to go on a rampage on their home turf, thats a completely different thing. Bayerns defense is also still shaky at best and Berbatov still good enough to score - there were much worse players scoring against Bayern this season, even when they were on a winning streak.
Robben and Ribery also dont mean automatic success. Robben is prolly still not in best shape, esp. after their decisive match vs Schalke on saturday, where he cant be rested. ANd Ribery once again played poorly vs the Mancs. It was however good to see that some 'minor' players like Pranjic and esp. Altintop had a good game, b/c that was rarely the case so far in this season.
Whatever, its a good starting situation for Bayern, but they are far away from being through. Really depends on Ribery and Robbens form again, not only physically but mentally. If they are able to come home from Schalke with a victory, the might kick out Man Utd as well driven by their euphoria. It could go however wrong if they take a loss on saturday. And i guess it could be similar with the Mancs match vs Chelsea.
