What Guardiola is currently trying with Bayern looks a bit similar to the hybrid 343/433 he used with us mid-11/12 in terms of defensive organisation and transition. Most notably against Madrid in the first league Clasico when Busquets was playing both CB and DM at the same time. Interesting for sure.
Interesting. In Pep's final season at our club, we used to switch between 4-3-3 and 3-4-3. Perhaps he wanted a permanent transition to 3-4-3, if he had stayed longer?
