Mikel Arteta hailed Arsenal's home fans for their 3-1 win against Tottenham.
Thomas Partey, Gabriel Jesus and Granit Xhaka struck for the hosts as Emerson Royal saw red for Spurs.
On the support, Arteta said: "They were phenomenal. We went from it and we created great energy in the stadium and deserved to win the game.
"With our way of playing we can attack in different ways. They [Tottenham] don't need much and you have the feeling that they can create. You have to live with that.
"But we didn't have that in the back of our mind, we were free, courageous and brave and this is what we demand from the players. It gives us a lot of encouragement and confidence to believe that we can play at this level."
On Gabriel Jesus, he added: "It's his winning mentality, the way he trains every day it brings confidence to the team and he has taken us to a different level."
While for Partey, the manager said: "We have been waiting for that one. For what he has been through I am so happy for him."
On the players, Arteta also remarked: "The players grabbed the game and deserved to win the it. It was the whole team - starting from the back to front. They really connected today.
"I hope this will give them more belief that they can win at this level in the way we want them to play.
"We have connected with our supporters and when that happens it is a really powerful thing.
"We have a really meaningful opportunity to give a lot of people happiness on a beautiful day and we have delivered that and it is a really great feeling.
"We are focussing on what we are doing. This is a sign that we are going in the right direction. We need to maintain that now and go for it.
"You feel the desire and humility - they haven't won anything yet and that is important to have that humility, which is a big driver for us."
