Dave, I don't know why I can't reply to your post. This system is *****!
I don't know what the FA rules are or why they have decided on the ten match ban. But I don't see why they shouldn't take the view "Suarez again. This guy comes before us rather too much. He seems to have anger issues or takes winning too far. Even his club says so. We need to set a deterrent penalty for him. What would a deterrent be? Well, seven matches in Holland clearly wasn't enough deterrent."
Or perhaps they simply observed Holland's seven match ban for a first offence, took that as a precedent, and increased it as it's a second offence over his career.
I don't know. You may be technically correct but I suspect most non-Liverpool fans will see a bigger picture than simply the FA can't penalise him for something done in Holland.
