Considering the player Arteta was, playing under Wenger and assisting Pep, his philosophy should be attacking football. Which fits the current players they have and what Arsenal have been doing for 22 out of the last 24 years. Emery philosophy whatever it was, doesn't fit what they've been doing at the Arsenal academy for years and years. So yes Arsenal philosophy is more inline with Citeh's.
It doesn't matter what players and funds Pep and Zidane had at their disposal, because others have failed with resources similar. It's the instant command of respect they received from the players and then implementing their ideas in to where the players either accept and enjoy or reject and hate and the results show that.
