Wenger was sent from the dug-out towards the end of the match after apparently becoming frustrated at what he felt was time-wasting by Sevilla captain Daniel Alves, but the Gunners boss insisted afterwards he had no idea why he was handed his marching orders.
"The player was down, and when the guy [physio] came on the pitch he stood up - and two minutes later he was sprinting," said Wenger. "The referee came to see me, and I asked him why I was sent off. He said he would explain after the game."
