I hate both players who do that, players who just have to put the arm on the back/shoulder of a player. That was never a yellow or a foul, just a complete and utter dive, felt the slightest touch, there was no pull, nothing to make him go down but threw himself to the floor. But there was no need to put his hand up, made the ref think he maybe did something though the ref shouldn't have bought it anyway.
Why do players insist on putting their hands up in those situations. Like when a player is backed into the corner, a defender will come in close in, stop but put their hands on the guys back, guy reacts, throws himself to floor and gets a freekick 9 out of 10 times.
