You have the top and bottom tier mate.Except that the history of the end was with the bottom tier
There was literally NO ISSUE at the Newcastle game; Half a dozen moronic Geordies wanted to get themselves on the telly by making out there was a crush - IT DIDN'T HAPPEN! About a hundred of the shirtless wonders had decided to stand together directly behind the goal, rather than stand/sit in their allocated seats . Any culpability aimed at SWFC was around the inability of stewards to persuade said meatheads to return to their seats, hence the further reduction in capacity at the insistance of the Safety Advisory Group, who basically wet themselves every time Hillsborough is mentioned for any reason. Capacity is down to around 33k these days, despite there behind 40k seats in the ground.
Hillsborough is tired and scruffy (some would say it's one of the last proper traditional grounds) and badly in need of updating (not going to happen) and the overall fan experience leads a lot to be desired (despite all that our ticket prices are higher than just about every other Championship club), but it's safe.
