The problem is how to provide an effective sanction in this case.
It's pointless 'fining' a multi-millionaire player.
Suspending / firing / selling him affects the club and supporters, but not him as he is a talented player and will be bought elsewhere.
What might make a start is for people to stop trying to brush this off as if it's some kind of high-spirited horseplay.
The Liverpool chairman referring to 'the lad' sends out a wrong message as well - Suarez is 26 years old and a multi-millionaire profesional sportsman, not a naughty boy who has misbehaved at a Sunday morning game in the park.
While there is so much money invested in a player like this, there will be no meaningful sanction because Liverpool, and the wider football comunity are keen to brush it aside and carry on.
The message which Suarez, like so many young men in his profession, is that he can do exactly as he wants, on and off the field, and the word 'No' is not something he needs to trouble himself with, because he never hears it.
