Io penso che gli arbitri non abbiano guardato lo schermo.
Se l'hanno fatto, perchè non guardarlo anche per il rigore che non c'era Maluda-Materazzi e per il rigore che c'era (non ricordo i giocatori, mi pare fosse nel secondo tempo) a favore della Francia?
In conclusione anche se hanno guardato il video IMHO non lo diranno mai a nessuno.
Well I think that referees didn't watch the video.
If they did it, why don't watch it too for the "no-penalty Maluda-Materazzi" given to France and for the "real-penalty" not given to France? (I don't remember the player involved in the tackle and the time, maybe in the 2nd half)
IMHO if they watch the screen to view what happened they will never say it to anyone.
I think that's time to use the moviola and insert it in the rules of soccer but only for the main episodes, like penalty, gol-non-gol (like the gol-non-gol for France in this World Cup) and episode like this of Zidane.
I think that "orange card" (timed expulsion) can be a good introductions, too. In this case Zidane red card and orange card to Materazzi
