Arsenal boss Mikel Arteta says he and Pep Guardiola remain close.
The Gunners have now twice beaten Guardiola's Manchester City this season.
Arteta told arsenal.com: We said goodbye to each other and we talked after that, like we do when we win and lose. That shouldn't change. Obviously there are different emotions for both of us but we should be able to do that.
Those games define the momentum of the season and, going into an international break, that momentum is really important. We played at home, we beat them in the Community Shield and we wanted to see if we had the consistency and the level to do it again against the best team in the world.
We performed to a very high level individually and collectively and obviously it was a very special day for everyone."
