I already said back in the match thread that you should have decisions more black and white as you can't easily read the mind of a player in many instances. Plenty of others have probably said the same in the past, people are very conservative in football though. The same with the obvious need for video instant replay checking of questioned goals. However I also said no hand should be allowed to score a goal and penalties should only be given where a very good goal scoring opportunity was prevented. Lame penalties are stupid and have players falling down nowhere near the goal to get them. Penalties should be a last resort rather than a first option for a player.
