Barça comparison? really? do you remember many offside goals, non pk called as pk, or our players distributing punches and kicks without a sanction? I remember the opposite. At least two legit goals disallowed, many pk's not called, and our players get sanctioned for anything. rm have had 2 pks where one rm player fouled the other, and it called a pk anyway. TWO, not one.
Sure I remember some occasions, but the way things work is that we have a much easier time remembering negative things than positive ones. That's why it's also easier to remember occasions of Real being favoured over them being unfavoured. If you would make up a balance sheet of Barca/Real x unfavourable/favourable calls, Barca might come out as having being treated unfairly on more occasions. But will it be a significant difference?
I had that blogspot which DonAK provided as my companion analyzing ref decisions in Barca and Real games, but after a while I had to seriously put it into question.
BTW: Out of curiousity, I remember the James pushing Modric incident but what was the other one?
Owh and about that incident: I think it was a legitimate mistake on ref's part.
Why? Imagine being a corrupt ref, why use an opportunity to make a deliberate incorrect penalty call in a situation where one Real pushes another when they are 2-0 up in the 43th minute?
If you plan on bailing out Real in a situation that stands out(own player pushing another) and facing possible consequences, at least wait for them to actually run the risk of compromising the game.
I know...I know.....there are no consequences for La Liga refs.
