The diving thing could be easily sorted in 2 ways.
1) Allow punishment after the refs decision, a panel should be able to watch the replay and punish the offender.
2) When player goes down like he has been shot 4 times in the chest and rolls about 4 times, they should be sent off the pitch to recover from the terrible hurt that was caused, 5minutes should do, their team would be down to 10men for 5 mins, no coach would allow that. If the player gets fouled, he goes down and gets back up. The ref will still award a free kick and the player will cease being a rancid diving ****.
3) We should all be allowed to shag Cheryl Cole. Not really football related but it would be good.
