Snowball We led Cardiff 1-0 and they "equalised" with a dodgy goal.
We led Cardiff 1-0 and 2-1 in Cardiff.
We drew 0-0 with Cardiff (without Kebe)
We beat Cardiff 3-0 on their patch (without Kebe and without HRK)
What difference does it make that you were ahead against them several times? You've also neglected to mention that Bellamy didn't play most of the first leg and none of the second leg against you, which seems like a fair comparison since you were without Kebe. Cardiff also had Ramsey playing for them when they beat us at the Liberty.
As I said in the other thread, you can prove whatever you want by choosing some nice selective stats. And quite what relevance our respective records against one other team have to do with the game on Monday I have no idea. Ultimately the only statistic anyone will care about is what the final score is on Monday.
