Nothing happened, there was no package/evacuation/football match otherwise the Health and Safety Exec would have have held a full investigation into how so many rules could be broken in the space of three days. Further if a premier League match was ever cancelled for such a stupid mistake the away fans would have been fully compensated for the money they spent on time and travel. Beside which we know all matches on the last day of the season have to kick off at the same time so how could anything have happenend ?
I think you must have read a malicous blog where someone has deliberately peddled lies to try and taint the worlds greatest football club. Next you will be saying that Ryan Giggs shagged his sister in law for 7 years.
