Former Premier League ref Howard Webb says Alexis Sanchez's opening goal in victory over Hull City was legit.

The Chilean scored both goals in Arsenal's 2-0 victory over Hull but his first came under controversial circumstances.

"It certainly came off Alexis Sanchez's arm," said Webb on BT Sport. "And to be fair to Mark Clattenburg he's gone over to the assistant to talk to him as well. I can only conclude that they came to the conclusion that it wasn't deliberate.

"And when we see it back I don't think anybody in the world who sees that sequence of play can say that Sanchez meant to handle that.

"If I was a Hull fan, a Hull player, the Hull coach I'd feel bitterly disappointed that I've had this really bad stroke of luck gone against me.

"But Sanchez does nothing other than try and play the ball with his left leg. As his left leg goes up, naturally his right arm goes up for balance. It pings around in there, comes off the keeper and hits his arm and goes in the goal.

"[It's] Certainly not intentional. The law requires the handball to be an intentional act and it wasn't. So as the law is written it was a correct decision by Clattenburg."
