I'm just a simple old man and don't really know as much about this football thing as a lot of you learned contributors.
In my ignorance, I thought, in the first half, we were moving the defensive set up of the opposition around the field, pulling them this way and that, sapping their energy, putting pressure on their emotional ability to concentrate. Stupidly, I thought they were visibly wilting after about 40 minutes and I was, silly me, confident that the foundations had been laid for the collapse of their defensive walls in the second half. Obviously, it was just coincidence that they did, in fact, collapse in the second half.
I'll try and be more attentive to what's actually happening in future.
