Arsenal boss Unai Emery had no complaints after their 3-1 defeat at Manchester City.

Emery admits City proved themselves a class apart as Sergio Aguero hit a hat-trick.

He explained, "They showed their superiority today over 90 minutes. Above all, the second half cost us. In two different times in the first half we struggled, but together we were defensively strong in some moments. We gave ourselves a chance so that we could hopefully take the chance in the attacking third against them.

"We also needed to work hard and not concede chances inside our box. In the first half, we can look at it with some optimism but in the second half we tried to do something different to go up against them by creating more chances, more opportunities, with more players and possibilities on the pitch.

"But the second half was different. We were more open than we were in the first half and they have very fast players in the transition. I think they showed today, with the possession against us when our defensive position was very deep, they can score like they did in the first half. When we needed to attack a little more against them, opening the space in the transition, they showed they were better than us at the moment. The result is the difference between Manchester City and Arsenal today."
