Keith Hackett speaking to 5 live:
"The reason behind that is that we appear to be changing the laws to accommodate weak and indecisive referee. Referees in the current laws at the elite level have the ability to caution someone for dissent and further dissent to issue a red card. They've also got a yellow card for stopping a promising attack. They put this under the banner of a cynical challenge, which is going to be introduced under the remit of a blue card and a ten minute delay."
Why is this guy insistent on hammering current referees? Any opportunity he gets. It's a tough enough gig with the criticism we get from outside of the community, we don't need it to come from those within or previously within the community, as it holds more gravitas.
