It didn't need that much more emphasis, but Bristol City's problems and requirements were brutally laid bare at Kenilworth Road at Tuesday night.
From a position of superiority in which they were visibly the better team, City conspired to lose 2-1 to Luton Town conceding the sort of goals that proved the genesis for the term "schoolboy defending".
Two crosses that should have been dealt with by the defence handed a way back into the game for the Hatters and all City's positive work on the ball was undone.
