There is legitimately zero chance that AEW sells out Wembley, and maybe a 2% chance that they even hit 40k. Tony can bring in Punk, Goldberg, Drew, Tanahashi, Okada, Sasha, Mike Tyson, Freddie Prince Jr, his mommy, his daddy, his two panty granny, the king of fuckin Siam, the state militia, LA Thunderbirds, ghost of Steve fuckin McQueen and ten Roman gladiators and they'll still barely manage 20k at best.
