I haven't really thought about the ins and outs of the Colo-Ba thing, maybe because there's nothing that can be done about it anyway. The main question for me is always 'have we been lucky there?' and the answer is no. We were the better team for the most part and were definitely deserving of the win.
If any Chelsea fans want to over-analyse anything, maybe they should analyse their spending, and ask how they didn't blow us out the water.
I reckon it could easily have been a foul, but never a red, fwiw.
