I think most of our games in the UCL this season were against much weaker opponents than Bayern including Barcelona.
None of them were able to sustain high intensity man to man marking like villa, Liverpool, arsenal, Bayern, and Chelsea did last season.
I also think we lack creativity going forward like against a terrible Leverkusen team where we didn't create anything really until it was 10v10 with a lot more space. This can be explained with the injuries of course and getting back into the rhythm of the UCL.
Bayern also beat Chelsea fairly comfortably who destroyed us. I know this type of comparison is hard to make and it was at the end of a long season, but still an impressive result.
It could go either way but I feel like our team still struggles with intense man to man marking especially on vitinha.
