No fence sitting mate - people need to stop looking at changing our game that has served brilliantly to this day.
No nothing re ET then pens plain and simple.
The 1 only change IF anything make it 10min halves.
What needs to be weeded out is the many other minor but time consuming/game flow halts.
Play acting, pulling of shirts, arms rapted around attackers in corners, cheating many years by the thrower and above all VAR needs to be stream lined and those ridiculous rulings of a thumb or your nose classified as offside.
Clean up these things the game will flow and more action than delays once players learn they can't get away with the cheats.
By the way - should a player be given a yellow taking off his shirt after scoring ?

I really can't see a prob regards it actually as long as it doesn't delay re start longer than it should.
