What Leicester are doing should not be possible, they've shown it is. I almost can't believe what they're doing this season. But that doesn't mean that the correlation between money and success is a lie or a coincidence. I seriously doubt Leicester will push on and dominate, the most likely outcome is their players will be hoovered up by the right boys and the status quo will be restored.
Don't mix up possible and probable. If I say it's dangerous to cross a busy road blindfolded and you do so and happen to make it that doesn't show that I was lying or the general principle of what I said was wrong.
All that said, it would be absolutely fantastic if Leicester were to win it, if only to show that it is possible. I didn't think what they're doing could happen in the modern game, it would be the best thing to happen in football for decades.
