You keep saying "key areas of weakness that haven't been addressed", in both this thread and the John Stones thread, it's getting old. Why not go flap to Pep Guardiola? Clearly he doesn't share your concern.
One single friendly with a starting XI completely alien to what you will see next week means nothing. Select players struggling to adapt to Pep's style means nothing. That we haven't brought in more defenders yet when the transfer window is still open means nothing. That Kompany and Otamendi were injured so Alex fucking Kolarov was playing CB, means nothing. Get over it, move on.
