tottenham the football club in question is based in an area that was previously heavily populated by people of jewish heritage and has attatched itself to this , it's fans call themselves the 'yid army' in defense of the jewish population in tottenham because the other fanbases in london (like chelsea who that reporter is a fan of) use the jewish heritage to attack them by doing things like imitating the sound of a gas chamber, the reporter themself is angry because the referee didn't give decisions that that favoured chelsea when tottenham played chelsea the other day that is where the gassing part comes from

the russia part obviously from russia invading ukraine but what links russia invading ukraine to chelsea is chelsea's former owner was a russian oligarch and the uk sanctioned him so he had to sell the club he is angry because the russian oligarch was very popular amongst the chelsea fans
