This red card/penalty thing is BS.
Robben has been denied a goalscoring opportunity, he gets a penalty. Why should Chesney not be punished for yet more terrible decision making?
Why should Demichellis not get sent off for taking down Messi yesterday?
When we played United last season under RDM, why should Branna not have been sent off for taking down Ashley Young?
The player has to be punished. If Chesney, and Demichellis are allowed to get away with it, and stay on the pitch then they will do it again.
Imagine if that was a Bayern penalty, no red for Chesney, he saves it. 10 minutes later, Robben bombs in again, Chesney thinks to himself, I can get away with this. He does the same thing again, because he knows he won't be sent off, or maybe he does get sent off. Thats incredibly unfair on Bayern too.
Why should he be allowed to make that error twice? He shouldnt, he should get sent off, he should miss 3 matches and he should lump it because no-one put a gun to his head and told him to go and take Robben out.
You cannot give professional footballers the chance to be repeat offenders on this sort of thing. Imagine how many players would get a JT knee up the backside like Sanchez or whoever it was did at the Nou Camp in 2012. He thought he would get away with it, he didn't, he got (rightly) sent off and it cost him the chance to play in the CL final.
Diving is no different. Players get away with it because the repercussions are that players get a bit of stick. Doesn't matter to WBA though that Rami earnt that penalty against them that he gets some stick. Steve Clarke is out of a job, imagine where he would be if the ref hadnt given it. Everyones only kicking off because its against the English teams. If Alaba or Dante had been sent off for a similar thing, no-one would be complaining. If Arsenal had gone to score 2 goals, it would be "clinical Arsenal knock down the defending champions" not "Bayern had a player sent off and Arsenal did what they should have done" (Nothing against Arsenal specially)
Banning players for their stupid decisions is the only way to get them to tow the line and keep them in order. Unfortunately even then it doesn't always work.
