Sat here watching re-runs of the Euro 2012 qualifiers, Cristiano Ronaldo has just gone tumbling to the floor, letting out an agonising scream after running into the tiny and ancient frame of Dennis Rommedahl. That, sirs, was a dive. Booking Rommedahl was the wrong course of action by the referee - play on should have been the call.
However, taking this as a starting point, should the referee have deemed it a dive, he would have been duty bound to book Ronaldo, but this is clearly having no effect on the diving pandemic across football. Therefore, we propose that an additional sanction be applied. Yes, by all means caution the diver, but also allow the person the diver claims fouled them to issue a kick in the ribs of roughly approximate force to the scream/contorted dive/number of rolls post contact with floor. In the example above, Rommedahl would have been coming off about an eight-pace run-up to elicit the same response as that which ensued after slightly getting in the way of the pouty Portuguese.
Seriously, FIFA, we're doing your job for you here.
