Liverpool fans would have a fit. Even though with todays ticketing systems it could not happen again as you simply will not get in if you don't have a ticket. Gone are they days when they would open up the exit gates ( as they did At Swindon in the league cup in the 80's for us) to let a mob in because the turnstiles could not cope and so is turnstile jumping.
Although I didn't seem to hear anyone calling for a ban on smoking inside stadiums after the Bradford fire ( which may turn out to be arson and not a dropped cig) as it was disrespectful to those that died, only in 2007 & not for that reason.
I also did not see any compassion from LFC for the dead of Juventus or them or any other English club calling for all seating after bad crowd control, fighting and a killing surge in Belgium.
Although I have the deepest sympathy for the families of the 96 and what the shit rag paper & the lying police scum put them through ( I was at the semi v Wolves when it happened to us) fans are not treated like cattle anymore.
A crush could not happen anymore than a crush could happen now if everyone stood up from their seats instead of sitting down. All the difference would be is that that seat would put up and then lowered for European games. There would not be 4 extra people occupying that space. Basically a designated area where people can flip back the seat and stand without being told to sit down. There would also be no way of the crowd surging due to the design:
However, safe standing will be met by Liverpool by what I can only say is emotional blackmail
