I'm no cynic said:
I doubt if he did allow it. The truth is that we were up against one of the three truly world class teams in the game, and we were playing them in the first of a six game mini league, meaning that it was important to get at least ten points on the board before being able to relax in later games. With this in mind, Bayern were already going to be up for it, and at the same time they would have been determined to put down a marker for a new kid on the block team such as City.
Your post basically amounts to "We were scoobied from the start against Bayern because unfortunately for us it was an important game for them so they really tried"
So I'm going to disregard any depth to this discussion too and simply say this -
No team containing players of the ability and statue of Hart, Kompany, Fernandinho, Yaya Toure, Navas, Nasri and Aguero should EVER be outplayed to that extent.
