Well, that was just an incident that I had to make a decision over and I did on the day, Arteta said. We as a team have some ways of working together, and this (Aubameyang's actions) weren't how we do that, so we made a decision.
We want them to make each other better, Arteta said of his two keepers. We are competing against the opponent, we are not competing against each other here.We are just trying to bring players that can raise the level of the player that is playing the position, the level of the tea...
It was a real commitment and purpose because you can tell when you are really doing it or when you've been told to do it, Arteta said.
