I don't see anything highlighted? I assume you mean my assumption about foreign fans? I did a quick Google search and found a study that said 109k foreign fans attended Old Trafford for live games during the 14/15 season - with 19 PL games and some cup/European games, a total of (more than) 3.000 foreigners attending Utd-City on March 8th doesn't seem unlikely.
It was just to show that it's very easy and arbitrary to single out Liverpool while there were plenty of other games going on just a few days before that CL tie. All games played BCD were instructed by government officials in those countries unless I'm mistaken. Decisions in a crisis like this have to come from the top down imo, which is why I find it ridiculous to blame Liverpool for not proactively prohibiting fans from attending. Which business would make a decision that'll cost them millions of income in the heat of the moment, without sufficient reports and evidence that it's the right thing to do? I'm fine if people want to blame the local authorities but given the timing, I doubt they had more of a clue about it than your average Joe at that moment. Which is again why I think it should've been done by the government, from the top down.
Awareness was indeed raising rapidly, a week later there were no CL games at all anymore, so in hindsight - yes of course it's obvious the game shouldn't have taken place, let alone with fans in attendance. But that's easy to say right now, and it's weird to specifically blame Liverpool for it. Blame the club for the furlough debacle, for the statement regarding the mayor's comments, whatnot, but this... Nah, not having that personally.
