Even though at this time Arsenal are more willing to spend a lot of money to recruit players, of course Arteta should not eliminate the basic structure of the Gunners who always prioritize their young players. However, since being handled by Arteta, Arsenal have slowly rediscovered their identity. I believe Arteta is very serious about the new season and is of course targeting the championship.
Arsenal's ideology of always prioritizing young players is indeed very good, but if Arsenal can't keep up with the times, of course they will never be able to win the title. We know that currently many successful English teams are funded by owners from the Middle East and with a fairly smooth process, they are able to be consistent in almost all seasons.
There are also new teams who are currently also finding a place in the champions league because they realize how important money is to recruit the players the club needs. From my opinion above maybe you know who I mean, but indeed all teams want good finances so they can get good players too and when the opportunity comes I think they have to do it and Arsenal did it.
