Find out what rule Alexis Sanchez broke at Arsenal this weekend
The Gunners' coach Arsene Wenger was angry with the Chilean forward for disobeying protocol
Arsenal thrashed Hull City 4-1 away from home but, although Alexis Sanchez struck twice, Arsene Wenger was not happy with the forward.
He took a penalty and missed it, when it was actually Santi Cazorla who was supposed to be shooting.
"It was Santi Cazorla to take it, I don't know why it didn't happen," Wenger told the BBC.
"Did Santi not want to take it, or did Sanchez take the ball? We have a pecking order, but on the pitch they have to want to take it. But he was not planned, Sanchez.
"I want always to know what happened. And [for it] to not happen again, we have to see why that happened. But overall, anybody can miss a penalty. You have to accept that. It happens to all of us ... and it's happened to Santi Cazorla as well."
