Manager Mikel Arteta says the turnaround at a "fractured" Arsenal "is a credit to everyone".
Arteta came under pressure after a poor start to last season and his side went on to narrowly miss out on a Champions League place to Tottenham.
But they go into Sunday's game against Liverpool top of the Premier League after seven wins from eight games.
"I'm really happy and proud for the change of dynamic and the atmosphere around the club," said Arteta.
"Looking ahead again at where we want to be - we are not there yet.
"How you measure success is lifting trophies, but as well you have to understand where we were and how fractured the club and the environment looked.
