I cannot believe how can anybody draw conclusion from those videos? Nothing is visible, nothing is clear.
I wouldn't blame neither the player nor the referee.
For those who are rushing to insult the referee, I thought he fell very convincingly. You know, when somebody knowingly falls, its different, they have their arms to cushion the hit. This was a legit fall. But then, there's a huge outrage from players of Benfica, so it may be that there's an exaggeration. In any event, the video is inconclusive.
