2. Does the apprentice finally become the master?
While the likes of Allegri may carry with them a long list of achievements, Arteta has something many other high-profile managers available to Arsenal don't: a unique combination of Premier League coaching experience and sound footballing education.
Pep Guardiola's start to life as a coach was eerily similar. The Catalan was lifted from relative anonymity when he was appointed as Barcelona's coach and hasn't looked back since. Arteta's stint as Manchester City's assistant coach will have prepared him for the rigours of the Premier League to a considerable extent.
Since the miracle that was Pep Guardiola, several clubs have tried to repeat the formula, to varying degrees of success. While Zinedine Zidane tasted unprecedented success with Real Madrid during his first stint, Thierry Henry's campaign at Monaco was nothing short of a catastrophe.
As with everything else in the beautiful game, there is a degree of uncertainty surrounding Arteta's appointment and whether his lack of experience as a manager could come into the picture.
While success is never guaranteed, one thing is certain: Arteta's knowledge of the game and tactical nous is exceptional, and his illustrious mentor has vouched for him on several occasions in the past.
