A grave error was made before kick-off of Aston Villa's crunch Champions League quarter-final second leg clash with Paris Saint-Germain on Tuesday evening.
Unai Emery's side went into the match 3-1 down from the first leg, but had hopes of reaching the last-four of the competition with the backing of their home fans after being second best in Paris.
The atmosphere was strong before kick-off, with a sold out crowd proving to be vocal ahead of a fast start in Birmingham. But it wasn't a fast start in terms of those in control of the PA system.
