Speaking after the defeat at the Etihad, Arteta described it as ‘painful’ after a good start to the game.
“Really painful, a lot of things happened in the game to get where we got.
“I think we started the game really, really well, and in the first situation, they had the ball wide of the box we didn’t defend the cross, we defended the run into the box really poorly, and we’re 1-0 down.
“Then we tried to go again, we created some situations, and we conceded the second goal.
“For me it was a clear punch on Callum’s face, the referee allows it to go, we are 2-0 down and after the red card we had a mountain to climb.”
