I'm still not convinced that this will be a good transfer for him. He won't play the same role in Bayern as he did in Dortmund, if only for his importance to the club. And I'm not sure why Bayern need him; it's always good to have great players, he adds depth and basically weakens the oponent a bit, but as I said, they have a very good striker already.
Let's hope you're right... No doubt about Dortmund's scouting talent; transfer policy/scouting-wise they have proven to be brilliant and one of the best clubs in the world. Especially looking at Mkhitaryan and Aubameyang now.Seeing how they substituted Sahin, Kagawa and Gotze and how they strengthened this summer, I would bet on BVB finding a substitute for Lewandowski before we find one for Puyol.
