Didn't go last night but thinking back to Saturday:
The only anti-English stuff heard was "it's coming home/you fecked it up" which in truth they did with 6 out of 7 games at home and being 3rd best team in Europe on FIFA stats - the only one acting as a host nation and in the weakest group to start with.
I'm sure our English academy kids can manage and just as long as Canton enjoy it being sung back to them when England do eventually win a trophy.
Regarding our Hymns and Arias, anyone singing that should be banned for a month until they learn the lesson. With all the different home fans and different away fans over the years it's likely to hit home for someone in a really nasty way when they should be supported instead.
