So a few take aways from this first week:

Bayern came to have some fun (Kane trophy curse?)
City are doing the same old score 1-2 goals and then just play out the match
Inter still can't defend for shit
Real are just testing things out and waiting for the season to start back up
Chelsea are happy to win, in any way
PSG just playing like the best team in the world
South American teams came to play

What did I miss?

EDIT; Messi can't hang with the big boys anymore, confirmed
