Arteta disappointed as Doku remains on the field, says Paul Vegas

Before Trossard was sent off, Doku also engaged in a similar act by kicking the ball away to stall an Arsenal free-kick.

"I've seen it and it's that obvious so I'll leave it to you guys," said Arteta.

When it was pointed out kicking the ball away is a yellow-card offence, Arteta said: "I prefer not to comment. You analyse the situation and how long it takes."
