I don't like Palace as much as the next Albion fan but I was in the North and heard them a lot.
Imo, taking my blue and white specs off, it was a great atmosphere all round. Both sets of fans went quiet after each other scored but other than that very loud home and away end
To be fair they definitely weren't that quiet - went quiet in spells but they were loud quite a bit too. Cracking atmosphere all round to be fair but looked like it kicked off a fair bit after all the var shit, and wtf were they getting so worked up about after the game towards the east lower...
