I thought that long-time reader Kent from Oregon raised such an interesting issue in his comment earlier, that I'm going to reproduce his point in full here:
Really, I'm wondering why players would ever put up with this? Soccer culture question: I get, but loathe, the rolling around and feigning injury by players. I don't get why players would ever tolerate someone spitting in their face and not doing anything about it? I don't like Diego Costa and all his (insert bad word here) antics and pretending, but the Betis player (I missed who) who came from off the screen and spit A LOT directly on Costa's cheek... absolutely unacceptable and, to be polite, childish. Not to sound like the aggressive American here, but if a player did that openly to another player over here, there'd be hell to pay. Check that, if just about anyone spit in another person's face over here, it would be a near immediate fight. It doesn't get much lower than spitting in someone's face. Costa? He just took it and complained to the referee again. I wonder sometimes if the play acting so many of these players do just disguises them from being such softies (polite words, right?). Imagine someone spitting on Vinnie Jones or Roy Keane? At some point, what's a fine. I'd like to see more of these guys stand up for themselves in a real way.
So, what do we all think? Was Amaya justified in sending a mouthful of saliva Diego Costa's way on the grounds that 1) he's on our side, and 2) Diego Costa is a horrible weasel? Or should he have just swung an elbow, knocked out a couple of teeth and taken the red card? And what would you do if someone spat in your face? Wobble your lower lip and call the teacher over like our Brazilian friend did?
From an Anglo-Saxon point of view, there's little more disgusting than being spat at, so I won't have much sympathy for Antonio Amaya when he gets the ban that they say is headed his way. As Kent points out, his action just seemed a bit childish. But if he'd gone for a studs-up last-minute hang-the-consequences lunge at any random point below Costa's waist, I don't suppose I'd have had too many objections. He who lives by the sword and all that... What do you reckon?
