While the results haven't been there, Arteta says the difference in performance is a big positive.
"We haven't done what we want in the Premier League in terms of results," the Spaniard told Sky Sports.
“What we have done in terms of performances compared to last year, the way the team is, the identity of the team, [the difference] is night and day.
“But results wise it has not been [what we wanted] over 38 games. We have managed to things we haven't for five years, winning against the top teams. But we are not where we want to be.
“In Europe we were very close, an inch, a post, dictates failure or success. That's what we have done."
