Nearest derby is on Thursday and chances of getting a ticket on matchday are close to 100%
As for the support: we've had a few really good moments in my opinion though it was a medicore game- with the sun constantly shining right in the eyes and rapidly falling chances of advancing with every passing minute.
As for your support- It was actually very poor if we take into consideration the amount of spurs' fans in the stadium (of course that's only my opinion). I don't recall any group that would come in high numbers like you did and remain silent almost throughout the whole game (maybe Blackburn). But there's a huge difference in demographics and model of supporting between Poland and Britain...
