Its a results-driven business and Arteta still needs to prove he can get them over the course of the season.
But anybody who watches football and knows the game can see that this particularly group of players is the best Arsenal have had for several years and they're also very young. 11 of the 14 players who saw the field on Sunday were 24 or younger and 6 of them 22 or younger. There is real change going on from the Arsenal we've seen the past couple years.
The top four looks unassailable anyway so this year should really be all about continuing the reset, laying a good foundation for the future whoever ends up managing the club, and getting back into the Europa League. You can say those are small ambitions and you wouldn't be wrong but once you've finished 8th twice in a row with a rotating clown show of veteran players in and out of the side, a youthful team that plays some good stuff and finishes 5th or 6th would be a breath of fresh air. You've gotta start somewhere.
