'I have never seen something like this penalty in my life'

Arsenal manager Mikel Arteta has been speaking to BBC Match of the Day following the game: "First of all, I'm disappointed with the result especially when we started the game quite well and scored a beautiful goal. Then we lacked control, gave the ball away and we didn't do the simple things well enough to be really on top of the game and have the dominance we required.

"The game was always open without really conceding anything."

On the Brighton penalty: "We are really disappointed with the decision that leads to the goal because I have never seen something like this in my life. He touches the ball as well."

On the second-half performance: "We did a lot of things not to the standard with the ball, so we didn't get any momentum. We never got set in areas so that afterwards we could generate chances and counter-press in the right moment.

"We conceded one chance when we had 10 players on the floor and [Yankuba] Minteh takes off. I think we have to do much better things than today and unfortunately we lost two points."

On Ethan Nwaneri: "Really bad news because I think we have lost him. We had to take him off at half-time with some muscular issues."
