If that was a pen at Liverpool then every game is going to have 20 a side. The Chelsea game was full of iffy decisions and didnt even go to review when should. etc. They are breaking their own guidelines with players and managers pressuring the refs and decisions that are not a clear and obvious mistake being reviewed and changed. I suspect If that hadn't been Liverpool at home it wouldn't have even been looked at. It will kill the thrill of football. The aguerooooooooo moment would lose its magic. It is so inconsitently applied it is not fair. Refs will feel the pressure from certain media outlets that means certain clubs will always benefit. If you cannot see that then you are kidding yourself. Sky and the bent betting syndicates will be loving the possibilities it brings. If i thought it would be fair and straight forward i would get behind it. As it stands it plays further into the hands of those who want to manipulate outcomes. Anything else is just naive wishful thinking.
