Still the toss (I presume) but going first all the way through to have a 60/40 advantage won't be an option - neither team will continually be playing catch-up. You seem to have some sort of objection to the ABBA system - care to tell us what you think is wrong with it?
The current system gives a 60/40 advantage to the team that wins the toss and goes first. So, essentially, winning the toss is the game-changer moment. Not good.
Sorry, I don't believe a word of this! Football authorities making a sensible change that actually improves things? Come on.......it's just not possible! Pigs will fly before that happens!
