Let's see. Luiz, Mustafi and Xhaka are the main culprits. Even if Arteta believes that they're the best we got, there are times when you need to put your foot down as a coach and show that frequent mistakes will not be tolerated and drop people.
People talk about Wenger's laidback club atmosphere, but what does it say and what sort of message does it send to the entire squad, when Luiz can make mistake after mistake costing us games and keep his shirt?
I see a few fans trying to paint Arteta as this sharp disciplinarian, but I have yet to see it.
Who could he play instead of Luiz and Mustafi? Honest question.
Holding? Coming back from a serious injury and has been hot and cold. Sokratis? Also coming back from injury, albeit more recently.
He could've sub Kola, but that's about it. His hands are tied here.
