I honestly think that this would be the best moment in UK MMA history... The time is right, it's a grudge matchbox end all others, Semtex has developed some TDD and Koscheck's chin is completely shot so there's a much better chance of it happening than it did before, and if he really knocks hin out, like flying gunshield/faceplant/Walk-Off KO's him dead on the ground then I might well shed a little tear of joy...
I've never wanted anything more in an MMA fight than Semtex to knock out Josh Koshcheck.
