I've seen the anti English taunts particularly in Scotland so let's not get in to English bias fans. In this case it's not nationalistic, darts fans love great players and Price is great player. His problem is he's so animated, so arrogant he has set himself up for the reaction he gets.
Could be the Covid travel limitations, which makes the crowd more local instead of international, but the English chants, booing non-english players on the World Championship is worse than ever and that is a shame. Normally, it was only that bad in Scotland and overseas!
Maybe go to Ireland. Hardly any Irish players worth chanting for.
