God, where do I start? Heading: yes, I understand the concerns, I really do, but there are few things in the game more thrilling than a diving header: the scorer diving full length to get his nut on the ball, ignoring possible injury.... It's a dying art already.
Go back to how the offside rule used to be - less than two players between you and the goal when it's played to you, you're offside, level means you're on.
Penalties for handball only when it's deliberate - all this nonsense about body shape and defenders expected to keep their hands by their sides or behind their backs when challenging in the box is stupid. Similarly if the ball hits your arm when you're in an aerial challenge it's never a penalty (unless you actively punch or palm the ball) - it's humanly impossible to jump without raising your arms.
Goalkeepers should not be a protected species: 50-50 challenges should be allowed anywhere on the pitch. Football is a contact sport, and every player is aware of it and revels in it. If they don't they should go play golf or something.
All these tip-tap three yard goal kicks are stupid too - the ball should leave the 18 yard box before anyone can touch it.
Get rid of VAR or use it properly - if the ref checks it and still thinks his decision was correct then that's it, end of story. No appeals.
Loads more stuff wrong, but that'll do - this old Dinosaur goalie from the best times (70s and 80s) is convinced that Arsene Wenger and his money-grabbing paymasters are ruining what should always be a simple - and yes, beautiful - game!
