Man, convincing our fanbase that Arteta is the next City manager will be pretty difficult. Eventhough it is easy to why it can be a good idea. Arteta clearly have seen/know inside and out our Club management.
Pep clearly rated him very highly as manager despite his form on Arsenal, many thought Pep statement is sarcasm but he genuinely think that Arteta is a really good manager have been working with him closely for years. Pep will not easily give him that kind of compliment if he doesn't think so. His standards is very high afterall.
It is not easy to judge Arteta true capability because Arsenal as club is such a mess, ranging from the top to very bottom there so many of that club problem to exist and Arteta as capable he is, can't do it alone yet he will the first figure to blame for Arsenal wrong doing despite not all of that club problem is from his. Trying to implement the style and instill the culture he have seen in City to Arsenal will be very difficult job and it will taken him for years to do it. Not an easy job and heck even Pep himself will also find it is very difficult to do.
Thing is Manager appointment is all about whether the manager in question is a match for the club itself. CV and experience is good but it will not matter if the manager philosophy and playstyle is very different compared to ours, for example Prime Mourinho despite his impressive CV and experience after managing treble Inter season will not match our club philosopy and style at all.
If CV and experience is all that matter, Pep and Zidane will not getting the job in their first big team at all and you know how it turn out (Sextuple and Three peat CL respectively).
CV is good just for assurance for fanbase that the manager itself is good enough to lead the club to the very top but not the major factor of why that manager must get appointment as a manager.
