Based on his confidence in accusing a top level goalkeeper of not knowing the basics of the game, I would guess that
@SadlerMUFC is less likely to be someone who has never kicked a ball in his life and more likely to be someone who
has played football at a low level. Because it's the type of thing someone who has played at that level says, totally unaware that the player they're commenting on is operating at a level so far beyond their own experience of the game that they might as well be watching a different sport.
Essentially, being somewhere adrift on Mt. Stupid:
Or maybe I'm wrong and he actually has never played football, in which case he should be congratulated on his confidence. Or, he's actually Peter Schmeichel and we should listen to him.
Edit: genuinely posted that before I saw him say he has played goalkeeper all his life and that he would have saved it. I am
so pleased with myself for guessing correctly.
