While they lead the pack in England, they drew 2-2 with Bayern Munich at home in the Champions League quarter finals.
On controlling emotions, Arteta told a news conference: I think it has evolved, I don't know if it is for better or worse. It's not me the one that has to judge that, in the end it's how much I help the club, how much I help the team and individual players to try to perform and win as many matches as we can. And this is the final objective, always."
On transmitting calmness to the players, he added: I don't know if it's conscious. You guys know me. It's how I feel. One way or the other it's very difficult to hide it. It's how I feel. I want to give the players the best support and mindset to enjoy this moment and go for it and have a real sense of belief and determination to go for what we've worked so hard for for 10 months."
