Whilst this behaviour does seem way over the top, surely when there are approximately 3 million welsh people and 53 million english people stuff like this is always going to be on a larger scale?
FFS stop making excuses for these pricks, you're not anti-English for criticising this behaviour
The above happened in Nottingham, which is a smaller city than Cardiff, surely going off your logic we should have had riot in the streets after we beat Belgium?
