The Rebuilding Phase has already started
Our club is at an important stage of rebuilding, both on pitch and behind the scenes, like fitness, scouting and footballing affairs. Everyone knows about the huge amount of signings to the backroom staff done by Arsenal in the last 2 years and that unlike our player signings, these were signing of the best people around. There are reports that Gazidis has tripled the amount of staff which proves that he is indeed preparing Arsenal for the Post-Wenger era. With Gazidis (who was wanted by Man City) being one of the best in the administrative role and Raul Sanllehi in charge of footballing affairs, 2 of the 3 most important roles in the club are occupied by the best people around. As you have guessed 3rd role is the manager.
Wenger will most likely leave in the next 2 years which would mean a huge overhaul of the training staff (who Gazidis was unable to sack and get better people since Wenger protected his outdated staff like the outdated manager he is) which if handled by Gazidis, Sanllehi and the new manager will be the best available. With a progressive coach who will accept the distribution of responsibilities instead of hogging all the power, it will bode well for the future of our club, plus with Mertesacker in charge of the club academy, lazy players such as Iwobi will be weeded out despite their obvious talent.
This brings us to the playing staff, in the last 2 years some of the deadwood (aka players) with no contribution have been released or sold but there is still some left like Perez or Campbell. A look at our squad will reveal that we have 5 important players (Cech, Monreal, Koscielny, Santi, Giroud) all 31 or above this year. Ozil, Wilshere and Alexis are out of contract. Walcott and Coquelin have been frozen out. Young players like Iwobi, Chambers and Holding are stagnating after promising starts. A HUGE MONSTROUS WORK awaits a new manager, though he will have good young players like Bellerin, Kolasinac, Lacazette, Ramsey and Mustafi to rebuild our Arsenal. Plus he will have a mostly clean slate to work with, so it is pretty much up to Gazidis and Sanllehi to get us a strong coach.
We will need great patience from our fans in one of the most delicate phases of our history.
Onward and upward Arsenal
