Something needs to be done about all the jostling / manhandling at free kicks and corners... not sure what though, short of awarding a few more penalties.
There genuinely seems to be a lot less of this in the World Cup, especially when compared to the Championship. There have actually been some decent headed goals from corners, something that has almost been killed off by all the holding and shirt pulling that is somehow acceptable these days. I can't believe it is that hard for refs to crack down on this.
