think Artetas' style is actually still the same as Arsenal's predecessor Arsen Wenger because nothing has changed drastically from the leadership pattern that exists at Arsenal. They always do it with their young players and indeed it has been imprinted from the start so they are not too far from the existing vision.
It's just that right now he's doing it right but in this condition that doesn't mean he can also relax because next season after they are in 2nd place at this time of course the pressure will be very strong.
What Asernal need is not change in their pattern or team formation, becais if you watched asernal closelin this season, you will noticed that their played exceptionally well from the beginning of the season and they were able to maintain that status quo for long up until the towards this end of the season, so Asernal is not a too much case to worry about and as a matter of fact their deserve our commendations becheir apply this same tactic in the next season and luck happens to be on their side, Asernal may become the title holder on the next season.
