Arsenal boss Mikel Arteta feels the club has now rediscovered their "soul".
Arteta admits he had concerns for his old club when assistant manager at Manchester City to Pep Guardiola.
He told Marca: "I was Pep's assistant at City, we were playing Arsenal and I saw that the soul of the club had been lost. There was no enjoyment, no feeling.
"I knew there was the option of of soon being in the other dugout and I knew we had to connect the team and the fans.
"It was very clear to me. I drew a tree and its roots, and I said that the problem was ours.
"We had to cure all that, and cure it with people who were involved. Without that, there would be no fun for the fans.
"Now I feel happy, we have a clear identity, there is unity and we are full of energy.
"That's the greatest thing. From top to bottom, everyone is pushing in the same direction. We give the fan something to dream about and be proud of. And now, we have to win more."
