You're right Chuny, but it would be so simple to cut it all out but it's as if it's become the accepted norm so it's ok now. All teams do it, Maguire dived last night expecting a touch and then embarrassed waved no it wasn't a penalty at the ref, but he still dived expecting a touch.
The ref's have been pretty good at playing advantage and it's amazing how many mortally wounded players have suddenly got up. It's a miracle I tell you.
There's so many simple things they could bring in to cut out feigning injury, cheating, time wasting, getting in the ref and asst ref's faces and so on. The ball might actually be in play a bit more then as well.
A few ideas off the top of my head
1) Any player arguing a decision in the ref or asst ref's face is an automatic yellow card.
2) Only the captain can talk to the referee about a decision.
3) Once the ref has given a penalty (and VAR confirmed if there is VAR being used) then the ref blows his whistle. Then if the defending players aren't out of the box in ten seconds they are booked. Same with keeper being on his line.
4) Fourth officials do substitutes and it can happen while the game is in play. They don't do anything else apart from get shouted at by the two coaches anyway so why not have them in charge of subs? No time wasting then, just imagine how quick they'd get off if the ball was in play.
5) Standing in front of the ball at a free kick is an automatic yellow.
6) The defending team have 10 seconds to get behind the sprayed line or the free kick gets moved forward to the sprayed line (not inside the penalty area obviously, but in that case can move it anywhere up to the edge of the box if they want )
7) A cynical hack down to stop a counter attack means a free kick outside the area anywhere the attacking team wants it, no matter where the hack down happened.
8) Goal kicks have 10 seconds to get back in play once the ball is in the keepers control or else a corner is given, similarly with throw-ins, once it's in the player's hands 10 seconds or the other team get the throw.
